Use Frontline from 8 weeks, kittens weighing at least 1 kg. Stronghold from 6 weeks, weighing 2.5 kg - 7.5 kg. Stronghold does have the added worming treatment but does not treat all worms so Drontal should still also be used. These are usually used as a preventative measure against fleas. If you already have a flea problem use Frontline Spray (available on vet prescription only) on kittens from 2 days old.
