Which RAW do I use?

[GovtLawyer]

I just got the Rebel XT, and I have PSE 3.0., which I willl upgrade to the Camera RAW 3.1. So, if I understand all this correctly, I have 4 RAW conversion choices. I have the ZoomBrowser, and the Canon Digital Professional Photo (is that the same or two different ones?) I have the Adobe Camera RAW 3.1 which I can access through PSE 3.0, and I have something called DNG, which I can access through PSE 3.0.

Assuming I am not too eager to purchase another stand alone product, what is the best way to process the RAW files. I will be shooting RAW + JPEG.

Also, can I batch process RAW, assuming the quality of the shots are the same and similar adjustments are required?

As a lawyer, you'll appreciate this answer: I really like RawShooter for conversions. ;-) It's free, too.
You can adjust one & apply the corrections to a group all at once.

GovtLawyer - please don't post the same question in multiple forums, i've answered this in the "EOS Digital Cameras" forum already.
