Greetings Tar.
The 'Mystic Wanderer' from "Magic of Faerun" might be a good idea. some of it's abilities are dependent on not wearing armour. You also get your CHR bonus to AC, as well as DEX bonus. Most of the abilities (gem magic & greater potion) will make you a good temp magic item producer. you also get a few (sleep, suggestion, charms) mind affecxting abilities. And a familiar to boot...
The contemplative (DoTF) would also be a good choice. At first level, you would get 1 of 2 new domains... which would have to be the Celerity Domain. This would give you +2 DEX (enhancement), +10ft speed (lt. armour), +2 initiative (enhancement)... all supernatural. This domain also has really good spells (cat's grace, haste, mass haste, time stop, etc.).
The Contemplative will also get you immuities to diseases & poisons, a second save vs mind affecting, lay on hands, spell resistance, and damage resistance, etc. And all you need to jump into this PrC is a 13+ rank in religion, and what good cleric wouldn't have that by 10th level...
Both of these PrCs add to your casting level also... Don't take a PrC unless it adds to your casting level.
I guess that's it for now...
