Work on the Medic Tool is #1 or so, can hold off on the max rank. AOE Heal is next what you should have a few points in, use it to heal groups or treat it like a HA's shield and pop before you turn the corner in combat. Revive Grenades are nice to have, but not required, but it'll let you reach the guys in the open or around the corner. C4 is very useful but i'd wait till you got the other abilities certed well enough.
Flak or Nanoweave for the armor, Flak lets you survive most things and would be better if you aren't on the front line firing back.
The Gauss Rifle is a fantastic weapon, I love the other medic weapons too but having the default works just fine. Gauss S is good for other situations.
