Three problems:
1. Your GameSpy ID:
If you cannot remember this, you can simply register another with GameSpy. If you know the ID but not the password, then you can apply to GameSpy to be reminded of the password.
2. Your Servervault:
You will need to be able to tell us your original GameSpy ID, so we can copy your Servervault over to your new ID. Without this, you will have to start again with new characters.
3. The Avlis passwords:
If you do not have these, then the easiest way is to reapply to Avlis. In a couple of days or so, you will get the passwords again.
Hope that helps.
