Cnidarians are the most diverse group.
Yes insects can be said to form the largest group of invertebrates with about a million species described and possibly several millions yet to be described. Of these, about 400,000 are the coleoptera (beetles).
The largest group of invertebrates is called arthropods, which includes insects, spiders, crustaceans, and other organisms with jointed limbs and an exoskeleton. They are incredibly diverse and make up over 80% of all known animal species.
Gastropods is far wrong. The "group" or "class" of the Phylum Molluska with the largest and fastest species are the Cephalopods. Largest being the giant squid, Fastest prob a tie between squid and octopus.

That depends on your definition of the word "successful." If you mean which group is more numerous and has populated more of the world, it would be the invertebrates. If you mean which has more higher intelligence, it would be vertebrates. If you mean which group is more essential to the food chain, it would be the invertebrates. If you mean which has the largest animals, it would be the vertebrates. It all depends on what you're talking about.
