Wiser Use of Money: Pay Off Student Loans / Invest

[Jurollo]

18k of it was a personal student loan at 9.25% now
18k is at 4.75%

I am assuming it would be prudent to pay the 9.25% now and then maybe pay the other off piece meal? I am contemplating just paying them both off as I would then literally have no monthly payments outside of a cell phone. I own my car free and clear and have paid rent for the next 6 months. Outside of poker, upon acceptance of a job offer I recently got I will be making $75k+ a year so the $400 I am paying a month now could get moved to investments as I move along.
