Concerning removing the center hole in all the ribs. It is a good idea to remove them all.

The reason is that when you applying the monokote, the iron will heat and expand the air inside, between the ribs. With the holes in the ribs, the heated air will move into other areas of the wing and not present a problem by 'puffing' the monokote between each rib like a balloon.

This is also true on a hot day when the plane heats up due the sun.

It really is standard and not a problem to remove them.

Nice pictures and great documentation of your build!

I have that same plane and really like it. Leaving the wheel pants off is a good idea. During a takeoff, mine came up through the bottom wing and broke the trailing edge and the back piece of a rib. Since I bought the plane built, I did not have an outline of the ribs to repair them. So, I must sand a replacement piece until it fits....just haven't done this yet.

It would be great to have a copy of your outlined ribs...

Good luck on your build!
