When bottom paint is rolled on, you get an orange peel effect. Doesn't
this add to the wetted surface? Also, how do you burnish bottom paint?

Depends on what kind of bottom paint it is but for the kind that
sloughs off and the growth with it -- You don't (burnish)

If you are racing or something where the smoothness of the bottom
matters, you don't use that kind of bottom paint and then you either
take the boat out of the water and wash the bottom off when it isn't
being used, or have someone scrub the bottom while it is in the water.
