Me again with a few "wingie thingie" questions. Yep! Got me another plane!

I purchased the Czech Model BV 40A (kit #4802 - 1/48th) and of course, I have some questions.
First off, anyone build this? Any things to watch out for?
The instructions, as plain as they are, do not discuss the interior coloring at all. So, what would the "cockpit" color be? The bench seat? The floor?
They do discuss the exterior colors but use RLM and FS numbers. And throw me for a loop: the box indicates three colors, yet the instructions list five.

For the hard/sharp edge scheme, which colors should be used? Any, to further assist me, what would the recommended RLM #'s convert to in either Tamiya or Testors acrylics?
Forgive me these questions, but it's a kool lookin' plane and I'd, of course, like it to be reasonably accurate.
Oh, one more thing....it shows rigging of sorts (NOT on the instructions) on the box picture, the quality is lacking and I can't really tell just where (other than it attaches to the axle and fuselage) the rigging goes.
For those not familiar with this engineless birdy, here's a picture...... BV 40
Anyhow, again, I bow down to those whose heads are frequently in the clouds (and I say this respectfully
