You can't get any gamerscore (g) from Halo Waypoint. The only things that can be got from Waypoint are avatar awards such as armour for your avatar.
You have to be an warrant officer in halo reach to unlock the helmet you also have to go to halowaypoint and unlock the armor.

Halo 3: ODST is the newest of the two, but not the newest Halo game.
The halo time line goes Halo Wars, Halo: Reach, Halo:CE (halo 1), Halo 2, Halo: ODST, Halo 3. Halo 3 and ODST are practically at the same time.
Halo 3 ODST is not for PC but Halo 1 and maybe Halo 2-3 are
After Halo 3 there was halo wars, halo 3 ODST, and Halo reach. A new company (not Bungie) will be making a Halo 4 and rumor has it there will be a remake of Halo Combat Evolved.
it goes halo, halo 2, halo 3, halo 3 odst and soon halo reach will be available
