You need to download the latest copy of ACR (Adobe Camera RAW) for your version of Photoshop. That will then let you easily include RAW images in your Photoshop workflow. In the past I placed a tutorial in the Digital tools forum for the workflow I use for RAW images. Here is the link:
This tutorial is based on CS2 and I believe that you probably are using CS1 (since you said version 8). There is a fair amount of similarity between the two and the Bridge part of the equation, but you'll need to allow for some differences. CS2 added a bunch of valuable stuff for RAW handling and the latest beta of CS3 has a whole bevy of new RAW features, so you may be close to the time you'll want to upgrade and you can just leapfrog from what you have now to CS3 (it will be out in a few months officially).
If you have any specific questions, just post them as a response in this thread and I'll try to help (as well as others).
I shot for years with the 10D and now use the 20D.
