I mainly get contracted for Press Conferences by the groups putting them on and sporting events so my workflow is quite different. You are shoot smaller number of images per assignment where i am shooting anywhere from 100 - 10000 images per event.
I recently decided to start working with the DNG raw file over my native Raw file because I am not a fan of side car files and I dont like relying on a catalog file to save my edit info. Check out this video to help explain what I mean. Of course this is for the Lightroom shooters out there.

I then import the new DNG files into Lightroom and am able to tag, keyword, edit metadata, edit etc from there. I use a RPG Keys keyboard to help edit fast in Lightroom! Fantastic product, expensive but its saves me hours of editing time.

From there I tend to batch my sharpening action in CS3 or if its a basketball game I have a batch action with Noise Reduction and sharpening.
I use a plug-in called IOpener Pro that allows me to build special batch actions and render up to 8 different file types at the same time. For example when I shoot a basketball game I need to run my NR + Sharpen batch but from that I need Full Rez Jpegs, jpegs for sales gallery so it adds my water mark and resized jpegs for uploading to animoto to make a slideshow. This is done all at once, I just have to press play! Its also has a process at a later time feature where you can add as many jobs as you like and have it start at midnight when you are sleeping its working!
IOpener Pro is a PC only program but I know there is a similar solution for MAC I can't remember the name right now but if someone is interested I can locate it.
Its also great for portrait and commercial shooters as it has speed keys build in for fast ways to apply any action or group of actions with a simple click.
