It wasn't for me, Commander was one of my faster ranks. Try playing Firefight Arcade or Invasion, they're both pretty fun and get you a bunch of credits.
as of right now, you can only go to a certain level. soon, you will be able to get many more levels(this weekend ;oct.9 maybe). you unlock the commando helmet at the rank on Commander. to see armors and what level they unlock at, go to http://www.haloreachers.com/halo-reach-helmets/ or http://loot-ninja.com/2010/09/27/halo-reach-armor-and-voices-unlock-guide/ have fun
