When you put condition into module under .../lib/RT/Condition/ then you 
should register this module in DB.

Last. Only if "UserDefined"

No. RT doesn't support running scrip code before action.

In 3.0.x stage select box appear by incident :) I can't explain all 
issues you should look at source code. Patch was on devel list and was 
approved for 3.2. I hope it's there :) didn't look yet.

perldoc Text::Template

One of the most desired feature. Dirk Pape has patch that add this feature.
