Spend some time on Portland Craigslist and your local Craigslist. How much could you get for your furniture and how much would comparable furniture cost? If you are a student, your probably don't have "nice" and "expensive" furniture and household goods, right? And you can take your time. You need a bed pretty quick, but you could pick up some folding chairs for $20 at target to wait it out for a couch and table and chairs.
On the cars, when you move will you need 2? If so, then it is probably better to keep them both. If you won't then selling one and driving one might be just fine.
I've heard cars can be "shipped" and that when shipped they can have up to 100lbs of goods inside. This is entirely rumors, so verify it. Perhaps ship one car, with your bikes in it. (Bulky and hard to pack around and expensive to buy used in the Portland area). Then load up the other car.
When I moved about 700 miles away, I shipped a very large suitcase by Greyhound. Slow, and unreliable in that it could take 4-10 days, but I think it was only $50 to ship my heavy sewing machine, and a bunch of clothes wrapped around it.
