Skill Trees:
Conjuration (all perks except soul stealer/oblivion binding)
Sneak (all perks except assassin's blade)
Archery (all perks)

I need some help picking one or two more skill trees (no crafting skills). I'm leaning towards pickpocket because I might RP this character as a kleptomaniac. Also, how reliable is bound bow at higher levels and/or expert? Will I need to switch to stronger bows in order to keep up?

Lastly, what's a good spread for this kind of build? I was thinking 200 Health, 200 Stamina, the rest Magicka.

Wow, never noticed how fast this forum is.

Go for illusion. Make the sneaking Mage type that mind controls

Unless you're going to loot-hauling, you shouldn't need much stamina. You sneak and shoot from a distance. Plus, you have summons to be meat shields for you. Most fights you get into should be over before it comes to melee fighting. (I know Stamina is used for zoom, but you don't need much Stamina for that really.)

You might consider Illusion. It has a range of spells whose sole purpose seems to be keeping the mobs off of you. Besides the crowd control (Frenzy and Calm), there's also Invisibility. Great for a Sneak Archer! Or you could go with Enchanting to make your gear stronger or (and I know you said you were avoiding crafts) Smithing for the same reason.
