My cat is going to give birth in about 1-3 weeks any advice?

She is a purebred Persian, and the father is a himalayan. The vet said she is going to have at least 3 kitties, 6 at most. After birth, how should we handle the kitties? Should we wear gloves or masks? How long do they just drink her milk? What do we feed them after? Should we keep feeding her kitty food after she gives birth? Do we have to keep the father away from they newborns? if so, for how long?
