Final Buying Help

[beergeek]

Hello All.

I have really appreciated the knowledge I have gained from this forum in guiding me through my first Home Theater purchase. I am concentrating on getting my audio setup together now and had a few questions on how to best spend the rest of my budget.

I will mainly be using my setup for movie/TV watching, but there will be some audio and game playing. I am by no means an audiophile I just want to get something that doesn't sound terrible at a decent price. I was going to get a refurb Onkyo 606 but spotted a deal yesterday for $369 for the 607 and I jumped on it (glad I did it is back up to $494 today!). I also have a old serviceable (I think) Infinity BU2 subwoofer I will be using in the setup.

Anyway I am trying to figure out the rest of my setup. I think I am going to get a pair of Polk Monitor 40s for the fronts. I think I would rather have the 50s (tall floor speakers) but the bookshelf is a much more convenient size for my setup, and my 18 month old is far less likely to topple them over . Are these suitable speakers for the front?

And next what is the best next purchase for my system? With that I think I will have a reasonable 2.1 system. Should I replace my aging sub? Add a center channel speaker? (CS1 or CS2?) Add some rears? If adding rears is the best bet, I'll need some fairly small wall mountable ones? Is there anything available at a reasonable price?

Any help is appreciated. This whole process can be a little overwhelming
