Why 10 ranks in Balance? 5, so you're not flat footed is the typical number.
Escape Artist is one of those skills that's nice when you need it but "when you need it" covers few enough situations that it's rarely worth the investment. It is also exceptionally easily replicated by various spells and items and also by having a buddy around to get you out of whatever you're trying to escape from (cut your bonds, kill the guy who's grappling you, etc)
Your skills look solid as they are to me. I would say Able Learner isn't really necessary just for balance (Martial Study in an appropriate discipline will get you balance as a class skill + a maneuver.) In fact, if it were me building the character I might ditch balance altogether (either live without it or wait until you take Scout levels to raise it) and put the skill points into knowledges or maybe sense motive since your wis is decent (all of which are class skills via Real Pilot.)
