Kevlar,
Good setup; I have in my office a Rotel RA-970BX (integrated version of your pre). The rotel will do you fine all through college, as you say. Not much better bang for buck in that price bracket.
Keep your system very portable (as it is now), otherwise you may be forced to sell components or leave it at home. I used monitors/bookshelf speakers through college, since I had to pack everything for a year into a full size car! But the system always went.
Do NOT let your system be used for dorm parties, if you value your components!
