Ranger allows for a lot of shifting abilities that let you get into sneak attack position, not to mention the quarry once per day.
Anyway, here's what I got. Bear in mind, our DM makes us roll for our stats, and I ended up doing pretty spectacularly.

lower.

Brutal Scoundrel
Hunter's Quarry 1/encounter
Nimble Reaction: +2 AC vs. opportunity attacks
Skills:
Stealth: +10
Thievery: +12
Perception: +8
Bluff: +9
Streetwise: +9
Intimidate: +9
Acrobatics: +12
Feats:
Backstabber (sneak attack damage is d8)
Warrior of the Wild (Ranger multiclass)
(these feats were ones I was considering)
Defensive Mobility (+2 AC against opportunity attacks)
Improved Initiative (+4 init)
Lost in the Crowd (+2 AC when adjacent to 2 or more enemies of bigger size)
Nimble Blade (+1 bonus to attack rolls when I've got combat advantage)
Weapon Focus (+1 damage)
Items:
Dagger
Cloth Armor
At 4th level, I'm planning to bump up Str and Dex, and using a multiclass feat to pick up a Ranger ability that lets me get into flanking position. I'm not sure whether I should get Cut And Run, or Evasive Strike...
I'm also debating between the brutal scoundrel and the artful dodger. On the one hand, I get extra damage with the scoundrel, but on the other, if I really focused on it I could get +8 AC vs. opportunity attacks by level 4, which makes the Ranger maneuvering abilities almost unnecessary...
