To answer your specific questions: 1) We didn't find a place to just drop in our tracking device and have it called every frame. We had to modify quite a few methods in in_main.cpp to tell the engine to either use our tracker (if enabled) or fall back to the mouse. Not a lot of code per se, just lots of modification to exiting conditional statements.
2) When you position the player, you are moving the feet of the player's model. You will have to figure out the transformation from the feet to the eyes (based on the model's eye height) to figure out how to put the "camera" where the tracker is. Also, changing the player's orientation doesn't change the view orientation. We found that we had to change the player's orientation (angles) as well as the engine's **ViewAngles** to get the behavior we need.
