"clean" starting point for custom-theme-set-faces

Hi all,

I'm creating a custom colour theme for emacs inspired by IntelliJ's Darcula. 
Work in progress here:

  https://github.com/fommil/unix/blob/master/.emacs.d/lisp/Darkula-theme.el


But there are a couple of things that confuse me about emacs faces, even after 
reading the documentation and I'd appreciate some guidance:

1. When a theme is loaded, what are the default "inherit" values for all the 
faces that I'm defining? Is there an implicit "inherit" based on what that face 
was before the theme was loaded?
   I've found that I need to override a lot of things with e.g. ":underline 
nil" when actually I want to be defining my faces from a clean slate, 
inheriting from "default" without having to explicitly write that.

2. How do I re-use attributes inside custom-theme-set-faces? I can't put the 
list of faces inside a (let ) because custom-theme-set-faces is expecting one 
parameter per face. Ideally I'd like to define a bunch of things in some form 
of data structure so that I don't have to repeat the values, and also so that I 
can parametrise the theme. (e.g. I could have a function that returns my theme 
with a permutation on font-lock colours)


Best regards,
Sam
