Honestly the only races I can picture in the niche of a Shaman/Witch Doctor are Orsimer and Breton.
Concerning Orcs, it would depend on whether you want to consider your character a "City Orc" or an Orc raised in a Stronghold who eventually left to pursue other interests. In Strongholds, "the only woman in the stronghold who is not the chief's blood relative or wife is the wise woman, the spiritual guide of the stronghold." Taken from UESP Lore Article on Orcs. So a female Orc would make alot more sense, but male should be okay too.
Concerning Breton, I don't really know anything lore-wise.
Concerning the Civil War, it's entirely up to you honestly. I'd think that the Imperials would surely accept you. For some reason I can't see the Stormcloaks wanting any magic caster fighting with/for them though.
