Prepping for FI - Rebuild?

My motor (2001 330Ci M54B30) has 170k miles on it. It has a healthy mix of hard driving and cruising. I am burning about 1L of oil every 700-1000mi. Other than that, I don't know what's going on internally (guess I need a compression test to really find out). My questions are as follows. Given the above:

1) Do I need a rebuild (basing this solely off the burning oil issue)?
2) How much is a typical rebuild just to restore the motor?
3) I want to go FI, but is there an work that can be done internally to make more power with boost while the motor is apart? If so, what? Cost?

I know prices vary for work like this, but I'm looking for ballpark figures or data from people that may have done a rebuild on a M54. Bear in mind, I am completely new to this so I really have very little knowledge on the subject of rebuilds.
