He created a preset in Lightroom to name his pictures logically when he brings them into the application:
So a file would look something like this for a shot he'd take today: 20080107_tampa_0001.cr2

The 0827 is the original file suffix the camera assigned. Then, when I output the image for various purposes, such as for web publishing, I add this:
Regardless of which method you embrace, now, at the start of 2008, is a good time to establish a useful file naming convention that you can use going forward.
