That's the standard Space Marine codex. It's a very competitive book (especially on the friendly play level) and is very friendly to new players.
I would definitely suggest mech'ing and melta'ing up. Get a Land Raider for your terminators (you're going to eventually want to arm them with Thunder Hammers and Storm Shields). And Rhinos/Razorbacks/Drop Pods for your marines. On foot, the standard Marine is just waaay too slow! They need to get in close to use their assault weapons (Meltaguns, Plasma Guns, Flamers) and from a Rhino, they can shoot out of the hatch from the safety of their transport!
Additionally, you may want to invest in a better
HQ, the Space Marine Captain is pretty weaksauce. I would suggest looking at some of the special characters. Vulkan is particularly popular. A plain old Librarian is a very decent choice as well, as the psychic defenses/abilities he offers are critical.
Vindicators and Thunderfire Cannons are great Heavy Support choices.
Truthfully, outside of a few nuts, the
SM book has very few "bad choices". You'll learn with time that there are some "Bad combination" and you'll learn which combination of units works best for you.
Good luck!
