Absolutely brand new to the speaker game, requesting lots of assistance!

Are you moving to an apartment? If so, is this location going to be permanent? When advising customers, I often tell people to buy the best that they can afford now for a 2.1 or 3.1 setup and then just buy some cheapo rears to complete it. Sometimes in apartments a pair of towers is enough base to even skip the subwoofer. My personal recommendation would be a pair of decent towers and an amp and then slowly buy the rest as you can afford it. Those Klipsch's are not very impressive in my opinon. Denon and Boston make a much nicer setup that comes with an amp http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Daps&field-keywords=denon%20boston&sprefix=denon+bo%2Caps&rh=i%3Aaps%2Ck%3Adenon%20boston for the price it is hard to beat, and the sub is very very tight. In my opinion that is about the last stop on the train before things start getting real and you need to start thinking long term with a setup. Also look used, for example I have a pair of Polk Audio TSI 300 towers, CS10 Center, Yamaha 5950 7.1 Amp, Klipsch S2 rears and I am trying to sell the combo now for around 700, and something like that would blow those satelite systems out of the water.

For something cheap, solid, and highly regarded, I'd recommend something from Pioneer speakers. Pioneer AVR + Pioneer speakers + Pioneer Subwoofer.
