Wow, that does seem like a convoluted mess, Maruice. 
It’s hard to help since you don’t give any indication of signal direction. Therefore it’s impossible to figure this out from what you’ve given us.
For instance:

A cable connects from the diplexer to a TSDA2150 signal combiner. One cable from the TSDM2150 connects to a Monster brand splitter. A second cable connects to the DVR 510 satellite receiver.

Combiners and splitters have three connections: A splitter has one input, two out; a combiner has two inputs and one output. In both cases you don’t tell us what is attached to which. Therefore it’s impossible to follow the signal path.
It would also help to know things like that purpose the VCR serves you, if the three TVs served by the second duplexer have their own sat receivers, and in general what you are expecting to get out the system (i.e., what you need it to accomplish).
RF connections are generally trickier than others. I’ve heard that with all the service calls a cable company does, it ends up being a problem with the cabling 90% of the time. Many times the F connectors are not terminated correctly, or are not tight enough. So basically it makes sense that the fewer connections the better. Also, all satellite cabling should be RG-6, from the dish all the way to the TV.
A few things do jump out as questionable.

Two dish 500’s are cabled to a SW21 3-sat switch.

I can’t find anything on a “3-satellite switch” at Parts Express, but I’m guessing it allows the two sat signals to be combined. OK there, although I can’t see the point. Typically the reason to have two identical dishes is to supply multiple TV’s. If that’s your situation it would have made more sense to just run feeds directly to the TVs.

The DSU-2 splitter has one cable connecting to two different TA15 amplifiers.

Unless you get a weaker than average signal from your dishes, the amplifiers shouldn’t be necessary.

A cable from amplifier #1 connects to a VC R. A cable from amplifier #2 connects to diplexer #2 in the garage attic.
Diplexer #2 in the garage attic connects to non-HDTV television sets in three rooms.

A VCR connected to a diplexer?? For what, so someone can watch a tape on all three of the TV’s? That’s nuts. As cheap as VCRs are it would be better to just get one for each TV.
What should have been done is spilt the signal from each dish and send an independent run to each TV. Assuming you have good service from the Terk, I would have split it 4 ways and combined the signal with each sat feed with the diplexers, to the three extra TVs. For the main system, I would have sent separate direct feeds from the dish and Terk and used a VCR as a tuner for the local stations (I really don’t like the idea of diplexing the two signals for my main system). If the local stations ended up weak I would have added a second Terk and done a two-way split from both. Or a 3-way split with one and the other direct to the main system.
By the way, no reason to pay a premium for a Monster splitter. Any splitter rated for satellite bandwidth will do.
