I found this tutorial helpful. It did seem though, that one point was overlooked. If you rename your wordpress directory, as the author suggests you do, you then need to go through all the files in directory and change all links that point to the /wordpress/ directory to the new name.
Update (12/14/2006) I just did a second install for a client – and this time, despite changing the name of the WordPress folder, I didn’t need to do a search and replace to reflect the name change. Odd.
