Questions on a Santa Fe F units build

[thoroughbreed]

I have been aquiring some athearn blue box F unit shells, both single and double headlight versions, and need to know a few things about building one of the blue-bonnets and a yellow bonnet:

What colors are needed for:
Blue bonnet?
Yellow bonnet?

Which colors do I need to lay down first?

Which decals are needed? I think I need the following:
Microscale 87-77,87-1188, and 87-101. Please advise me if these are correct.

Also, which horns are needed? Any detail kits available?


I'm looking at the following locos:

and number 338: <!-- m --><a class="postlink" href="http://www.railpictures.net/images/d...1290138287.jpg">http://www.railpictures.net/images/d...1290138287.jpg</a><!-- m -->

So, what are the detail parts I'll need? Does walthers have a F7 detail kit?

Thanx for any info,
