Are you good with XP's Registry? i would like any help on how to costomize....?

i was wondering if there was any registry hacks where i could use to:

1)move the systems clock position, so it can come off of the taskbar

2)completely remove the taskbar

3)change the colorof a font

or basically ANYTHING that allows me to costomize my XP's look in any way!! THANK YOU SO MUCH!!Are you good with XP's Registry? i would like any help on how to costomize....?
Basically you have a lot of tutorials on the net on how to do it, but I would really NOT recommend you to play with your registry.
