If you don't remember the backup password, there's nothing you can do to access that data. Passwords are for security, next time remember them.
You can use http://support.apple.com/kb/ht1212 to restore the device, but everything that hasn't been backed up without a code or password(purchases excluded) will be lost.
After restoring, you can redownload your purchases using this: http://support.apple.com/kb/ht2519
