For instance, if i pay $5,000 vs $10,000 in student loan interest, do I get a bigger tax break or more money back if I pay $10,000 vs $5,000? Or is it capped at a certain amount once you pay a certain amount of money?

The Student Loan Deduction allows you to deduct up to $2500. In 2007 I paid well over $2500 in interest and obviously want to take advantage of this.
