I have added an introduction to scripting in Blender 2.5x, including step-by-step development of a complete working addon, to the “Noob to Pro” Wikibook. The section starts here:

Glad it’s of help. 
I’ve just added another page http://en.wikibooks.org/wiki/Blender_3D ... ttings_New explaining how to implement the recommended Object→Action→Settings convention (perform action first, then let user adjust settings). Turns out it’s a lot easier than the bundled scripts would have you believe.
