Great build, Sofaking, it's really starting to take shape and it looks very authentic. I have a few greeblies that I might be able to donate to the cause, I'll have to take a look at what I have and what I can part with. I'll post up pics when I've gathered everything up.
Btw, for lights, have you checked out Grainger's? When I first started reading this post I did some searching for the infamous little dome lights and I stumbled across Grainger's which has all sorts of industrial type of light of the sort you see all over the place in Star Wars. The lights in question are called pilot lights and come in all sorts of sizes and styles, and while it may not be practical to buy all of the lights you need from Grainger's (they run ~$7/piece) it's still worth looking at and may give you better serch terms. Here's the link:

On the subject of greeblies, have you thought of putting some joke greeblies carefully hidden on parts of your builds? Nothing big but I was thinking of small toys like parts of broken Transformers, GI Joe, or even better would be bits and bobs from old, broken Star Wars toys.
