First off, Abberant Blood feat (the one that's fluffed as gangly limbs for +3 to grapple) + Inhuman Reach feat (+5 ft reach, -1 to attacks). He'd probably need to be a changeling, but in whatever low ECL fashion, qualify for Warshaper. Go up to level 3 for another +5 ft reach. Possibly level 4 for fast healing, not something directly represented in the games, but something that seems thematically appropriate. Fo base class, monk, unarmed swordsage, or some combination thereof. Swordsage is best though, as it gives access to Desert Wind for all the "Yoga fire" stuff and Shadow Hand for teleportation (earlier than Monk gets Abrupt Jaunt). The two disciplines even have stances to hover off the ground!
At higher levels, consider Warblade dip or feats to get Dancing Blade Form stance (another +5 ft reach, only on your turn, though), though that might be overkill.
