Commanding Voice is good. Master of 1000 Faces...depends. The big problems with it are:
Assensing (which spirits and dual-natured being always do) sees right through it.
It takes a really long time to activate compared to either more mundane things like programmable facemasks, or the simple spell Physical Mask.
As a social adept, you are fine. I am not a big fan of Master of 1000 faces, and I think a better way to be a social adept/master of disguise type is to instead be a Mystic Adept and be good at Illusions.
Given how heavily you are focused on social skills and stuff, I would think very hard about being an Elf.
Your main problem as an infiltrator is that you run into an impassible barrier if there's a maglocked door between you and where you need to go. You can get around this with social skills sometimes but it is still a flaw.
Facial Sculpt 2 is silly. Take Facial Sculpt 1 and, if you really want another +1, Improved Ability (Disguise).
Cloak sounds good but, unfortunately, is not. The easiest way for people to bust you is Assensing which this does nothing about. It won't really stop search, either, and without Counterspelling and with 3 willpower, you aren't going to be resisting many active detection spells. Improved Ability is a better place to spend power points.
Gear: SR is full of widgets and you may or may not want widgets. I am not a big fan. If you want the gear to do infiltration, you need:
Armor - I recommend a combination of Form Fitting Body Armor (arsenal), Holo-wear (Attitude), and SecureTech PPP (Arsenal)
Gecko Tape Gloves (for climbing)
miniwelder (cut through things you can't otherwise bypass)
2 crappy commlinks, one to run your stuff, one to broadcast your fake SIN
fake SIN
Sensory gear (take a look at some of the characters in my signature for examples of sensor gear setups)
at least a month of some lifestyle
a cheap vehicle
