Altering This Gallery+Thumbs. Who's Good?? (actionscript 2.0)

[Playdo]

I'm not an actionscripter but an artist with limited actionscript knowledge. For over two weeks now I've been trying to get a piece of code together but keep running into endless brick walls. I would have thought this would be easy but there hasn't been anyone out there capable of showing me the final solution so far.

I'm looking for a result similar to this tutorial http://www.republicofcode.com/tutorials/flash/xmlimagegallery/ but with a few specific changes. I haven't uploaded my attempts at the code because it probably will complicate things.

The source files are located at the bottom of this link: http://www.republicofcode.com/tutorials/flash/xmlimagegallery/7.php

What I am trying to acheive is the above gallery but which specifically does the following when a thumbnail is pressed:

- Show the preloader (whilst keeping the current image on screen).
- When the preloader has finished then fade the current image to alpha=0
- Slight Pause
- After the pause fade the next image in to alpha=100.

- In addition I've been trying to get the thumbnails alpha to be 50%. Then on onRollover and onRelease to set the alpha to 100%. Similar to this: http://www.republicofcode.com/tutorials/flash/imagegallery/

If anyone can actually do this then please post. But don't post unless you have tested and confirmed it.
