if i were you, i'd get something more fun than the bose's. sure they sound nice but in my opinion, you can't move a volume of air without having a good size to begin with. for the same price range, you can probably get a decent speaker system of other known brands like B&W or even Infinity. there are several names for receiver/pre-amp you can choose from such as NAD, Krell, B&W or even yamaha if u're tight on budget.
if u still insist on buying a Bose, i advice you go and find somebody who's an alumni of MIT. all ex MIT students are entitle to special discounts from Bose. last time i heard it was 50% off.
