Were it me, I would (with a human of 12+ INT and 10+ CHA) take 4 monk/1 Bard/10 Dragon Disciple. You already have the draconic language, all you need is drop 8 Skill Points into Knowledge Arcana. (6 Base from Bard, 1 from INT, 1 from Human). At level 15, when you're a half dragon, with an additional +4 to STR, +2 to CON, +2 to INT, wings, natural attacks, a breath weapon, blindsense, and whatever other goodies you get as a DD or through dragon apotheosis into a half-dragon, at that point, I'd think about whether I wanted more levels of monk, which, if I did, I could probably PrC my way into (Tatooed Monk from Complete Warrior, or somesuch)
