Bob,

Don't sweat the gauges, they will look fine and do the way you have them.

You must cut the cockpit out before you glue in the ply formers, the fuselage is plenty strong.

I have attached some pictures to help explain things. After you cut the cockpit in the fuse, you need to add some 1/32" ply or flight skin for the anti-glare shield, or dash if you are driving a car!

You have the formers in correctly, I set it up so the cockpit floor rests on the bottom of the rear former and on the top ledge of the front former, look at the pictures closely.

You can use the stock servo tray with the cockpit, I just had to raise the elevator servo 1/4" with some ply strips. You can clearly see them in the picture.
