It sounds like you bought Amano shrimp. Is your tank cycled? If not, then you'll more than likely loose the shrimp since their sensitive to ammonia and nitrites. The plants are jungle val and anubias, just be sure not to bury the rhizome on the anubias. It would be good to tie it to the driftwood (and tie down the driftwood so it's completely submersed) so its roots can attach to it.
