Money matters and I need help

I know I need to do something with my student loans before June (July?) first, but I have no idea what.

I have a Sallie Mae loan that's at 8% percent (which are actually two loans for $7,000 and $19,000) and a Direct Loan that is at about 3ish percent (one loan for $26,000).

I called the Direct Loan people and they said that by consolidating them, I get the average of the two loans. I have no idea if either of the rates are locked in, or how I do that, but I assume that if the Direct Loan is locked, I should leave it and consolidate the Sallie Mae one with something else.

Any suggestions? I'm lost. :(
