If you're using Lightroom, then there's no need to keep a "finalised" version. Non-destructive editing means the original file is intact and you're just writing instructions for the app to render the image the way you want it. You can make duplicates, for variations such as black and white, or different crops, or whatever, but essentially you only ever have the one master image (some refer to it as the negative because of this).
I use Aperture, but then I tend to go against the flow with these things.

My workflow is like this:
1. Take some awesome (and a lot of not so awesome) pictures.
2. Import them into Aperture. I have a preset that applies basic processing like saturation and definition on import. I also import them into an existing project, or create a new one as required.
3. Rate the images, discard the duds.
4. Rate the rated images to pick the best of the better.
5. Add keywords, titles, captions. Aperture and Lightroom make this a breeze.
6. Make final edits, retouching, cropping.
7. Upload the results to Flickr from the within the app/export to a format for sharing elsewhere.
(I often throw the exported formats away once I've shared them. I keep everything in Aperture for my own sanity.)
I have various projects under way. Anything that doesn't fit into an existing project get dumped into a generic project for sifting when I get bored.
Does that make sense? In reality, there's no hard and fast rule you should follow. Do what you think works best for you.
