Oh wow thanks! Ok then I'll just get the two floor speakers and that subwoofer since they match.
I'm not sure how the floorstandeers and subwoofer "match" like that since the subs are usually labelled a different series, since as far as the sub is concerned they'll match based on the crossover setting you set on the HT receiver anyway.
In any case, you can get two pairs of the standmounts and buy the center from that series. Although yeah, I'd prefer floorstanders too. But make sure the floorstanders you buy have a center in the same series otherwise you'd have a problem getting the center channel later.
Actually, you might as well get the mains, center and surrounds all at the same time, since it can happen that the series gets discontinued while you're saving up.
That receiver is a tad bit expensive would that be overkill for my setup?
The Marantz NR15xx and NR16xx are consistently rated well, sometimes even over fullsize receivers. You won't get overkill of power but you'd get cleaner power. Other brands have improved amplification quality but Marantz and Denon are still a little bit ahead.
No I dont plan on going 5.1 anytime soon if ever, is there a 2.1 receiver you'd recommend?
There aren't really 2.1 receivers save for some more expensive 2.0 receivers that come with a mono preamp output for the subwoofer. These can cost around $400 for the Onkyo network receiver to $600 for the NAD D3020.
What sources are you going to use? If you'll use a BluRay player with analogue output you don't plan on going 5.1 at all you might as well run stereo equipment and put some more money to the speakers, preferably towers. Get a used NAD or Rotel, then maybe get a sub that has high level inputs.
You can get quality towers now and decide later if you still want a sub since some of these can go down to 35hz, and if you can't shake the house with a sub anyway, there's not much for it to do but simply fill in the rest of the way to 20hz (5hz if you use a 15in sub for watching The Conjuring and Annabelle).
...I guess my size requirements for the receiver are making it tough for me to find something good.
So here is the updated setup:
Polk Audio Monitor 60 Series II ($150 for two)
Polk Audio PSW10 sub woofer ($80)
Receiver? (~$150)
Or try these - depending on what sources you use and how you want everything hooked up you'll at least get a lot of clean enough power out of this amp, and you get floorstanders for not a lot of money:
