Wing Incidence - adjust to get the fuselage flying at the angle you like.

Tail Incidence - adjust to remove any elevator trim once you have set the CG and done your downthrust checks

CG - mine is on the rear of the wing tube and has a very very slight pull to the canopy in down lines

Engine thrust - My C50 is lined up with the nose ring

What are my incidences in absolute terms? Haven't a clue and don't care! In my opinion you are wasting time adjusting any of this before flying. Fly it then adjust to suit.
