Thanks for the compliment! I'm glad you liked it.
I see you found the answer to your original question in one of my posts.
As for the other questions, you might check out http://www.endusersharepoint.com
. Lots of Dataview and client-side scripting articles there.
There are also alot of articles around (including on the site referenced above) on using JQuery to enhance the SharePoint experience. While there are some good tips there, I would be cautious about using JQuery to directly manipulate the individual rendered components in standard SharePoint list views. Much of the information used for that is not formally documented by Microsoft, and is therefore subject to change.
