stick with
Deafmetal's suggestions, it will do you very fine.
a Jackson guitar screams heavy metal. it has an edgier sound to it, I don't know how to explain it. it's just not the kind of guitar to play blues, Jackson is a metal guitar. great sound and reliable as shit. try to get you one.
for the multieffects, the Zoom is a fine cost/benefit one. cheap and versatile as heck. if you mix some of the effects with your amp's distortion, I assure you, you will be happy.
and for the Amp, let me recommend you a Marshall one as well. try to get yourself a Marshall MG10CD. if you're gonna play in a dorm, you don't need more than 10W, trust me in this one man. you won't be able to put your amp on full power unless you want people to throw stuff at you.
and this amp has something cool on it: you can use it to play a CD on the headphones and jam with your guitar at the same time. it's awesome to learn and pick those hard-ass riffs, good for a student. and not too expensive, cause it's 10W.
with this set, you're all ready to play your ass off in your dorm.
as Frank Zappa would say: "shut up and play yer guitar"
I wish you luck, brother.
