Non-setting books not yet included (that may or may not actually have PrCs):
PlzBreakMyCampaign - I already did this, via the PrC page on Wikipedia that sorts by book. Here's the (non-setting) ones it lists we haven't done yet, with ones you have in bold...
Cityscape, Complete Champion, Draconomicon, Dragon Magic, Dungeonscape, Fiendish Codex II, Ghostwalk, Heroes of Battle, Miniatures Handbook, Shattered Gates of Slaughtergarde, and Weapons of Legacy.
They list setting-based books separately, so you'll have to check that yourself.
