Itunes is asking me for a password when i go to restore my new iPhone with my old iPhones most recent backup. none of my passwords are working for it, what could it be, am i missing something very obvious here?

You very likely established an encrypted backup in iTunes. You will need to remember that encryption password, or the backup will not be useable.
If you can't remember the password and want to start again, you must perform a full software restore and choose set up as a new device when iTunes prompts you to select the backup from which to restore.
The above comes from the "encrypted backups" section here:
