re Doc:
Remember that you can jab his pills, and pretty much the match gets easier for you. Both characters have great gimping games, so you want to try to get doc off the edge, and at a relatively low angle--if he recovers from above, his recovery becomes somewhat decent.
Also, he can't cape your recovery, which although doesn't really matter, makes it harder in some situations for doc to edgeguard.
Watch out for his d-air, as I'm pretty sure it wrecks bowser's anti-air game, and instead stick to up-bing out of shield. In fact, bowser's fortress can really shut down doc's grab game (his other strength) if done at the right times.
