Move the xml files into their own directory  
Use one copy of the unsigned zone default (don't have a duplicate zone in each test)  
Create separate tests that run daily/weekly  
Come up with a naming convention for the tests  
Come up with a plan for how to track what the tests do (spreadsheet/wiki)  
Merge existing tests where possible  
Need a script that can do some consistency checking of the signed zones  
Create functions to handle generic tasks like setting up the environment and starting and stopping the system  
Could we script switching between databases rather than having 2 conf.xml files  
Perhaps a bit more logging when things go wrong? ("String not found" log message and cat the offending log file)  
Is there any way at all to set the tests up so that jenkins displays a matrix of each test case against platform??
