If you have access to the bloodline feats in Dragon (I think they were in 311 and 325), they provide a great way to bring flavour to your sorcerer by explaining where the magic comes from - for instance from an ancestor who was a chaotic outsider - and tailoring the spells known list slightly to reflcect this.
It looks to me that they also provide a "power-up" on a standard sorcerer, in that you get an extra specified spell known per spell level, at the cost of never being able to know certain spells (for example, the chaotic outsider bloodline gives you an extra "chaos friendly" spell known [e.g. protection from law] at each level but means you can never know spells with the lawful descriptor).
I've always wanted to give it a try because it looks like fun.
I'd also suggest maxing out your escape artist skill as much as possible - even to the extent of a one level dip into rogue (or taking human paragon from Unearthed Arcana, if available).
My NPC sorcerer just had a very, very bad experience with an Evard's Black Tentacles spell cast by the party and I've promised myself that if I ever get to play a PC sorcerer I'll try and minimise my vulnerability to that dratted spell.
