Restating the Paradox

First i'd like to get a definition of omnipotence. Does God have the power to both 1) heat coffee so hot that he can't drink it and 2) be able to drink all coffee no matter what temperature? 1 and 2 contradict each other so either omnipotence doesn't exist, or omnipotence is defined as the power to do anything that is logically possible.

With the refined version of omnipotence it seems possible that God could create a world where free will exists. If I want to ride a bike today God can't stop me because he gave me power to prevent him from controlling my actions. But if God is omniscent then he knows that i want to ride a bike today. Can free will exist if God know what i'm going to do but can't decide directly for me?
