At 6'9" , it may even be a bit small, but that's what extended seatposts and stems are good for. I think you may have a good bike there for starting out with, might change those stem shifters to bar ends or thumb shifters. Other than that, an overall greasing of the bearings in the steering tube, bottom bracket, and wheels will help get this bike ready for the road. Seen people (okay, me) start out riding on a lot worse bicycles.
