Only a couple problems with that stock list. First, mixing two types of clownfish in a moderately sized tank could easily lead to aggression and possibly death between them. Pick one type and stick with that . Clowns do not need anemones to survive at all, and having a nem in a new tank owned by a new reefkeeper under at best moderate lighting is a recipie for disaster. Stay away from the seabae nem . And last, sun corals are non-photosynthetic and will require direct feeding of live brine/mysis/bloodworms/other frozen at least twice a week. If you're not willing to frequently feed them with a turkey baster, dont buy them. If you're comfortable with that, go ahead and get it.
