As far as wild shaping prcs go, you might also want to check out the Warshaper (CW).
Hierophant harkens back, at least in name, to 1e druids in Unearthed Arcana. If you can use homebrewed prcs, you might also consider the master of hounds, though you lose all your druidic advancement in favor of a dog pack. Masters of the Wild is chock full of 3.0 druid prcs, most of which are cool- I dig the verdant lord, for instance.
If you're set on wild shaping, there are some good animal buffing spells in MotW, Complete Divine and Complete Adventurer iirc.
