Well, for starters, if there's an unbalanced triple splitter, (-3.5, -7, -7), the modem should be on the split line with the least amount of signal loss (-3.5 db) rather than the -7 db. Each splitter will cost you at least -3.5 db of signal loss, so if you can eliminate any of them, that would be good. Any unused ports on the splitters should be terminated.

I’ve seen the Commscope come up a few times. Are you suggesting those items based on the signal strength that I had posted?
Would the commscope need each output terminated too, like a splitter would?
And is there harm in splitting a signal after the commscope if needed?
I’m tempted to try it, just to see what happens, but I only have one coax running to my DVR and Modem (every other TV has a home run coax available). I can try running another coax to the modem, but it may be tough...
Techs will have it, stores won't. Yes any open ports is ideal to terminate if you can. Before you order anything, double check that you have power available for the amp location, there's a special splitter necessary for remote power if you don't.
Excellent. Hopefully it helps my situation.
I’ll just order the 9 port model that you pictured and some termination caps. At least then I have room for expansion (but I’m sure by the time my wife lets me get a new TV, it’ll all be wireless anyways!!!)
how much is the no-gain amp? it might be cheaper to get your home runs done and use current splitters at the home run point temporarily and call Comcast for a service call. comcastAndrew might be able to verify if price to correct wiring trip charge $60 would cover the amp.
