Or you can just play what you're playing with;
Item Familiar for untyped +lol bonus to sleight of hand; or a huitzil familiar if you want your familiar using wands and scouting for you.
Criminal Background or Apprentice (Thief) feat(s). At this level Apprentice would become Master (Thief) and give you a minion.
Sticky Fingers in a wand (UMD is nice to have so your familiar can use wands, in any case). Improvisation is another great spell-in-a-wand. Or you could use bard as the entry to Unseen Seer and get both on your spell list.
Finger Blades for the mundane plus 1, although i'm unsure whether that would stack with a masterwork skill tool.
Etc etc.
13 ranks, +5 dex, something like +30 from your item familar (do not lose your item familiar), +5 magic item of sleight of hand, +2 mwk item, +5 for improvisation, +10 from sticky fingers and without anything else you've got +70 to sleight of hand for picking pockets.
