Default HELP!! Edge 540 Geometry is wrong, do I change it?

I have a Wild Hare Edge 540 73" span plane that I just bought second hand. The plane looked mint when I bought it and have no problem with it. I stripped the covering because I want to cover it in the Red Bull air race scheme..
With all my planes I check every angle and measurement, I figure that if the plane is all squared I have a good chance on the maiden flight and most importantly aerobatics are nicer to perform.
Am I worrying about the geometry to much? Here is what I found.

Wing tips measure 11mm different to the tail end of the fuz

-Right wing tip is +1/2 degree

-Left wing tip is - 1/2 degree

-R/H Elevator has a twist of -1/4 to + 1 degree

-L/H Elevator has a twist of -1 to -11/4 degrees

Looking from the back end of the fuz, by eye, lining up the the horizontal stabiliser with the wing the left hand side of the stabiliser is down by 1 1/2 degrees.

I can change it all so it's all squared up... but will it really make a difference?? It will probably take about 5 to 10 hours to fix.

The bloke that I bought it off said he didn't get on with it. I suppose it was a bit unpredictable with this geometry.
So what I'm asking is, will it make a big difference?

I thank you in advance for any advice!

Forgot to mention in the photo, this is the right hand side and the left side is reversed, the gap is at the back, ie. the tube in the fuz is on the piss... (not square to the fuz).

I know this is an extra but it's the colour scheme I'm after..
