The procedure you describe is advocated by Dov Isaacs of Adobe, and his 
instructions also include selecting Binary encoding and TIFF 8-bit 
preview. I don't know if the current version of Snag-It, suggested by 
Art, includes those options.  In my somewhat geriatric version of 
Snag-It, the only setting for EPS is colour-depth.

But I'm not sure there's a great deal of benefit if you're starting out 
with screenshots, which are low-res to begin with. Photos and other 
types of graphics may benefit more from the treatment you describe.

(If you're monitoring this thread, Dov, can you comment?)

As far as scripting your current process goes, you can automate at least 
part of it by using the built-in macro-recording feature in Photoshop 
(Window > Actions) to open a new RGB window, paste, flatten, save as in 
folder... etc.

HTH,
