I'd bring the Wis down to either 14 or 12, then bump your INT up to at least 12. More skills, Yo'
Make sure to compensate your UMD score for your negative charisma modifier. I.e., give them 27, rather than 25. UMD is based off of your modified skill score (which includes charisma)
Couple questions though;
Why 7 SD? As a 20 Monk with Mind spell immunity, slippery mind is useless, and your Shade summon will get stomped on anything that it tries to attack at higher levels. -- Go for 21/6/3
21 monk at least gives you +70% Movement speed!
Why no discipline?-- YOU NEED DISCIPLINE
If you want them to be evil, I'd recommend Assassin. You can add +1d6 Sneak attack from an item to your sneak damage, plus you'll have the small probability to paralyze your enemy, which is always a plus.
How on earth are you getting 4 Charisma? o.O The lowest you could possibly get is 8, which minus your subrace would be 6
Swap Lighting Reflexes for Blind-fight.-- Much better, and your Reflex save will be Uber high anyways.
