Should go soldier if you're just looking to race through the game. Bring Tali or Garrus for your decrypter and whoever else you want. Soldier is untouched in ease of play, with all 4 weapons open to you, with assault rifles being the most powerful and fun to do weird stuff with and once you do the specialization mission you can chain immunity to become invulnerable.
In ME2? Pick whatever, you'll be allowed to change class from your ME1 saves, and there is more to the classes now. Me? I'll be infiltrator. >
