Looks good, though you might consider dropping a level each of Scout and Mystic Ranger to take dips in Cloistered Cleric and Swordsage. You obviously know how valuable Travel and Knowledge Devotion are, adding Child of Shadow Stance would give you a nice defensive boost, and 6 maneuvers would add a lot of versatility for you, especially since you could take it late in the progression to get high-power no-prereq maneuvers. Mountain Tombstone Strike is the most important of those. A second level in Swordsage might be worth giving up another level for, for the AC bonus.

As for feats, Improved Skirmish and Improved Favored Enemy are always nice if you want more damage and would be worth taking low-impact flaws for.
