For a receiver, maybe also consider something like a used Pioneer Elite (43/45tx, 5_tx, etc) which should come in at way, way under your budget. As a college student w/ needs for "just" 5.1 I'd also guess you don't have a cavernous space to fill, etc. Looking for used deals on quality stuff like Pio Elite (or Rotel, Outlaw, etc.) can get very decent processing, adequate power, and money left over. Something like the 4X & 5X Elite series should be going for no more than $350-450 (or even better) and does 5.1 as well as anything. The latest & greatest is often just the latest - carefully selected used gear can get you huge bang for your buck. You might have to do a little research and have a little patience but the reward will be worth it.
Budget sub? Hsu would probably be #s 1, 2, and 3 on my list. I've used Hsu and it really did the job.
If you do go the used route (eBay or Audiogon, etc. and haven't done that before), I'd also suggest trying for something via local pickup. Either that, or check for quantity & quality of feedback and make sure you're comfortable parting w/ the dough.
