Run Rename machine script and model specific Post Imaging Jobs by querying model

Good afternoon.  We use DS7.1 to push a ghost Image (.gho) file to the machine.  The techs need to Rename the machine to match our internal asset tag number (not stored within altiris).  2 questions:

1.) I'm looking for a good script that will prompt the user for the computer name and rename the machine from the minint- to the asset tag name

2.) The techs then run a model specific driver job for that model machine.  Any way to automate this by sending the return code of the model and using a condition task - if return code = model X run the post imaging jobs?

Thanks for your help and your time.
