It may not matter now, but if you're gonna buy something new, you might consider the fact that this new TV's gonna last a long time and could easily go into your bedroom or somewhere else in the house later after you upgrade to a larger display for the main viewing room.
Also, maybe you'll some day decide you don't want to keep paying $$$ to the cable company (or wish to enjoy the free network stuff in higher quality). FWIW, if you stop paying for cable service, you might easily buy a new entertainment center to accommodate a much bigger/better display too.

For us, we own more than enough DVDs and BDs to not also need/want to spend loads of time watching all sorts extra, lower quality stuff on digital cable/sat service. Also, depending on your exact situation, you might find that you can pull more digital broadcasts w/ a modern OTA tuner (built into a new TV) than you ever could (in acceptable quality) back in the analog OTA days -- of course, this will certainly vary according to individual location, etc. For us, even w/out cable/sat, we now have 2 dedicated fulltime kids digital OTA channels between PBS and Qubo that air kids shows (w/ maybe 80% cartoons) on top of the regular PBS channel -- and that covers a lot of the need/wants for us as far as network TV programming goes. Sure, it'd be nice to get stuff like Discovery HD, etc., but I'm fine w/ just buying the best such programs on DVD/BD instead. And of course, there's the internet and whatever multimedia edutainment content for PCs, etc. on overload nowadays, so there's far less need for that kind of content on TV. But that would be part of our consideration for whether to bother or not w/ cable/sat service.
The thing I'm concerned about is getting a set that will display my DVDs properly. Especially my Doctor Who DVDs. That's a major criteria in whatever I choose.
Beyond what's already said, I'd recommend seeing how they look on the sets for yourself -- although this is not as easy as we sometimes make it sound. What exactly does "properly" mean to you though? What kind of lighting environment will you be in? Brightly lit room?
Now, if the entertainment center wasn't a problem, what would be an appropriately sized TV for the 9 foot distance I'm sitting from it?
That may depend on how much SD vs HD content you'll be watching and what kind of quality expectation you have, especially for the old SD stuff.
For HD, I'd go for 60"-plus -- we have a 61" DLP RPTV and watch it from ~9ft away (eyes-to-screen) for a view comparable to being in the rear ~1/3-to-1/4 section of a decently set up theater.
For SD of rather old content, 60"-plus will likely look like crap to you, especially if you're not used to that size from that distance. Even the best SD DVDs will look a bit soft though they can still have a film-like appearance to a good extent, eg. the Star Wars OT DVDs and Lord of the Rings EE DVDs still look pretty good at that size, but definitely much softer than you're probably used to seeing. Most folks moving up that much in screen size will find the image way soft -- and also revealing (and sometimes exaggerating) all sorts of artifacts that used to be hidden by their former much-smaller display.
If you need something that yields a good compromise, especially if you don't plan to watch lots of HD content anytime soon, and also don't need a size that comes close to a real theater experience, you might be better off going for something in the 40-45" range instead (at least until you're ready for something much bigger and will have lots of HD content to watch). Not sure what your current TV size is, but sounds like jumping to say 45" would already be a pretty sizeable jump. And if/when you decide to go bigger again, that 40-45" display may well still fit fine elsewhere in the house.
You might also want to consider that whatever you buy now may continue to be the main display for the old 4x3 SD content if/after you upgrade later too since most of that stuff (at least the video-based stuff) will probably never look good on a big screen -- well, maybe someday, it'll be easy enough to just display them in a reasonable windowbox mode rather than enlarge to full height (as is typically done) so that all the PQ deficiencies of the old content will remain more or less hidden.
