The Flip-flop hub is a necessity. But also, those are just my guidelines. At BVV, we're racing 4 races per night, at a max. It's way less gear changing than it looks.

Contis and WTBs are almost always tight. The more of the bead you can get in to the rim channel the better they'll go over the rim. It won't be easy, though. Gluing Conti tubs are the WORST.
