identity theft?? what can i do?

To sum it up:

someone from my cosmetology school installed a keylogger on a poorly protected company computer. they got my information (ssn, date of birth, address, etc) an also managed to log my keystrokes for my aol email acct. one day my cousin called, said someone was on my screenname and i tried logging in, and they changed my password. not only did they change my pass on my aim, and email, but my online banking and credit accts as well.

well my husband is a bit 'pc friendly' and sent an email to the person hoping theyd send one back, and they did. he got ip form there. we then suspected who it was and direct connected to THEIR screenname, and got IP. SAME IP, same person, it was a person from school.

well we told the school and i flipped out on her behind closed doors in the office, and sort of threatened her, out of extreme rage that she did this and i had proof. well, 2 days later, school did nothing, and terminated me for the threat!!!!?

what actions can and should i take?
