So.... how are Norm and Max going to survive?

That depends on whether or not they can keep the base up and running. They have a prefab/geolithography plant, which means that they can replace hardware items fairly easily, and that goes a long way.

As for Norm...I shouldn't have to point out all the debate there. My personal opinion is that since there is no evidence as to how long it was shot and how bad the wound was, we have little to go by, and its survival is really a toss-up. We also don't know how quickly Na'vi blood coagulates, how well Na'vi tissues and organ systems respond to shock, or most importantly, where major veins and arteries run in the upper body. He could get lucky and the bullet could have gone through an area without large blood vessels, or he could have even gone out to the body itself and done something to keep it from dying. We just don't have enough information.
