Best Anaglyph colors

Hi!  This is my first posting, although I've been following closely for the last month or 
so.  I am very interested in doing some 3D stuff, not just photo, but also computer-
generated.  I just bought Truespace by Caligari (a "3D" modelling package), and what 
I am wondering is:

1.  If I create a "3D" object in Truespace and save two  images of it from two 
perspectives (L and R, presumably as close to 2" apart as I can get -- per a tutorial I 
read on someone's website), then I perform the necessary operations in Photoshop for 
overlaying the images with the R/G values properly handled, can I expect to get a 
decent-looking anaglyph (true 3D)?  If not, why not?

2.  If I create the object in color and do the same thing w/o converting to greyscale, 
what colors should I use for maintaining the best quality color anaglyphs?

3.  If I produce two .avi (movie) files of the object 'flying' at two 'cameras', 2" apart (this 
is just an example -- I'm not one to further the misconceptions about 3D), is there a 
good software package that anyone has used (maybe Adobe Premiere?) that will allow 
me to overlay the movie files and perform similar manipulations as the plain images?  
What sort of quality can I expect from this?

4.  How closely do the color values I use to separate the image views have to match 
the glasses I have?  Presumably, the closer the match the better the 3D effect, but has 
anyone had any experience with better effects from poorly matched glasses filters/color 
separations?

Thanks in advance, and sorry if the terminology I use confuses you.

My 2 cents on 3rD Rock:  Little Ceasars was out of glasses and I was unable to get to 
the store for some Barq's, so I watched with a Red/Green and a Red/Blue pair of glasses 
I had.  Based on the description that the right lens of the 3rd Rock glasses was greyish, 
I wasn't expecting to see too much in 3D.  However, the R/B did provide for some nice 3D 
when the feathers flew around, and the globe was spinning in the foreground.  Anyone else 
use R/G or R/B glasses?

Adam
