Help! Screen Sharing not working, other related Mac problems (1 Viewer)

My Mac Pro (2009) & MacBook Pro (retina, version 2, 2013), both latest Yosemite, were not touched by me in over a month (I managed to fall by accident and break my head (dumb luck), spent well over a month in the hospital, have been back at home since Monday, but still without proper glasses (I broke my reading glasses along with the head; re-bought them last Sunday, but FedEx which originally promised to deliver them yesterday is now sitting on the in NJ until Tuesday, for no reason I can come up with, and which is making reading, etc. difficult))
Anyway: first thing I did when getting home was running App Store on all my Macs and loading all new updates including Yosemite 10.10.1 Pretty much the next thing I tried doing was connecting MacBook Pro to Mac Pro via Screen Sharing (launched through Finder) something that had been in constant use for many years, without any problems ever. This time it refused to connect at all.
Connect As also failed with "Connection Failed" (disk drives were not being shown at all). The only connection that does work as it always did is SSH via Terminal.
Went on Mac Pro trying to see if something was changed or disabled, checked on System Preferences/ Sharing/ Screen Sharing/ and saw nothing wrong. One thing however is wrong, and I haven’t figured out how and why to fix it: The MP is itself being labeled "Ted's Mac Pro (2)" instead of "Ted's Mac Pro" as it alway had been. Repeated attempts to remove the (2) on its System Preferences seem to work, but then it gets put right back on.
I did check my Mac mini (which had been turned off during my entire absents) and it had the same problem, labeled as "Ted's Mac mini (4)". Totally bizarre.
If anyone has any ideas on how I can fix this and get Screen Share and Connect As working as they always did from MacBook Pro to Mac Pro (not the other way around) please let me know. I'd be very, very grateful!

OK, I think I found out at least part of the problems on the Mac Pro, not ready to read thoroughly enough until my glasses arrive to fix it, but yes, my Mac Pro runs off a Mercury PCIe OWC SSD under Yosemite, and indeed almost died (stood hung for hours) when I was mounting OS X 10.10.1 the day I got back from the hospital, but it did eventually boot so I kind of thought it was because it had been left siting there for over 40 days, and forgot about it....

Probably I am the only person at HTF to have run into this bad mess

Ouch! Glad you're healing up, Ted! I'll read your tech troubles tomorrow and see if I've got any insights.

There is some misleading information on that link. The only people at risk for that issue are those that used third party software (Trim Enabler) to enable trim on unsupported SSDs. Those using 3rd party SSDs without Trim Enabler shouldn't have any problems. I suppose there could always be the occasional firmware bug that needs an update but that isn't what they are talking about here.

The article mentioned an interview with OWC's CEO, Larry O’Connor. In the interview, O'Connor talks about this and says OWC SSDs don't need trim. So trim shouldn't be enabled via that third party software.

Your OWC SSD should be fine unless you had installed Trim Enabler.

Thanks, Keith, you do seem to be correct according to OWC: http://blog.macsales.com/21641-with-an-owc-ssd-theres-no-need-for-Trim
Also, I have absolutely not played with Trim, unless some piece of software did it without me being aware (any idea of how to check?)

The crisis is that somehow the Mac Pro has gone from being 100% rock solid, day in and day out to a long bunch of problems:

1) When I got home, the first thing I did was loaded all my Macs with App Store/Updates full upgrades including OS X 10.10.1 (up from 10.10.0). Went fast on MacBook Pro, loaded very slowly on Mac Pro, and then at one point shut down the machine all together. I rebooted, (pressed button on the front of the Mac) it again didn't finish booting for a long time, and shut down for a second time. Repeated reboot, this time I sat for what seemed like forever when in what was clearly above at least an hour if not two it booted successfully with no visible errors. I haven't dared reboot it since.

2) Screen Sharing & Mac Pro label not working/broken as described above.

3) EyeTV not working in loading existing (any) apps. EyeTV has been replaced by an external TiVO, so has done no recording for many month, but has an entire 4TB disk drive totally full of old recordings (for instance a vast amount of music videos .eyetv files). No clue why or how to fix it -- the obvious test would be to copy a couple of .eyetv files and test opening them on a different Mac, but can't due to Screen Sharing not working.

4) My Lower bay BD/DVD/CD RW has suddenly stopped launching to the Mac included professional DVDs, etc. : it has function perfectly before, always, indeed very frequently, because since our last Oppo stopped functioning, I've strictly use the Mac Pro for playing our 2500+ DVD/Blu-ray collection, not to mention CDs etc. Of course it could have died on its own due to a wild coincidence, but I doubt it.

5) Backup to its normally correctly functional Time Capsule - Time Machine Backup is being reported as not having succeeded in 40 days: size isn't an issue, the SSD is the only drive connected and is 480 GB (and mostly free, in fact because I moved lots of software out of it a few months ago).

I am pretty much clueless about what thing(s) went wrong and how to fix them. Like I said, I am horrified of even trying to reboot it without confidence that it won't just hang is I try. Unless I get assured that the PCIe SSD is not at fault, my beast bet is to try booting of a regular HD, where my only choice is OS X 10.8.4 which is what I was running when I purchased and switched to the SSD. I am scared there of the ancient software launched from its own ancient Application damaging current content. Sure I won't start anything, but I am pretty sure its iTunes launches on bought up automatically.

Again, any and all advice appreciated. Advice on any one of the problems is better than none.

PS. Please excuse me if I have mistyped or badly written something -- it will probably take me 6 months to get the effects of my injury on reading/writing/all words for talking get fixed. (The good news is that other stuff, like listening, walking, professional photography, getting back into my Iyengar Yoga practice seem to be at close to 100%).

Update:

1) Most likely is in fact some OS X cleaning that takes for ever on non-Trim SSDs (if not actual Trim) during OS 10.10.x updates.

2) Terrible Yosemite 10.10.x bug. See: https://discussions.apple.com/thread/6625266?start=0&tstart=0 and http://forums.macrumors.com/showthread.php?t=1804719

has hit many Mac owners, is sometimes fixable through much work (I did manage it, eventually, after hours of work) but very likely to go wrong again in days.

3) Fixed

4) Dead, unfortunately -- ordered a new Pioneer

5) Related AirPort unresponsive. Waiting for nothing to be running before I started pulling everything out.
