well I re-read your email, and I'm not sure I answered your question ;)

If you wan't that if a user enter a low-case text, save it as uppercase,
you have to modify RT code.

For the unique value, you wan't that if a value was entered for a
ticket, it cannot be used in another ticket? If so, you would have also
to add this check in RT source code ;)
