It's going to be a snap since you have two weeks - that's a lot of time. Just start with the things you don't use on a daily basis. Books, decorations, etc. Find one area to put the boxes in that is out of the way so you don't feel so cluttered. By the end of the first week, you should be down to bare bones, like just the things you need on a daily basis.
And label really specific - I did what room the box was going to and what was in it, like "Office - Eric's Textbooks." That way when you move in, you can dump the right boxes in the right rooms, and know what to open first ("Master Bath - Toilet Paper") vs. what can wait a month or so ("Living Room - DVDs").
We always unpacked kitchen, (master) bath, and bedroom first. That really makes it feel like a home, even when there are tons of boxes hanging out.
Good luck!!
