Hiya!
You can report your hacking here:
http://www.gaiaonline.com/gaia/report.php?r=1You might want to run a virus scan on your computer as you might have gotten a keylogger. You could have picked it up anywhere, it isn't really your fault.
If it wasn't a keylogger someone might have just gotten lucky and guessed your password. All I can say is try to make it more complicated once you get your things back. ^^
I was hacked a while ago, you will probably be able to get your stuff back. It just takes a little bit.
Do you happen to have the trade history? If you do, screen shot it and send it in with your hacking report.
Hope that helped, and I hope you get your stuff back.
