Are you getting a govt. loan, or a private loan? for stafford loans they don't look at your credit, but you can't be in default on another loan.
For a private loan you have to have really good credit, but yes, you can get a cosigner if you alone don't qualify.
For general info, look at:
education loan sections of most bank/cu websites
specific college websites, under financial aid
lender websites, like Sallie Mae
Many people here know more than I do (*waves at Drachen*), so that's all for now! Good luck!
