Finding these vb names

[Opserty]

UserID can be found on the "Edit User" Page in the AdminCP. Or by going to the persons profile and looking at the address in the web browser it will something like member.php?u=XXXX with the Xs being a number. (That number is the UserID).

Username is the username which matches the above UserID I guess.

I presume the UserID and Username are that of the Adminstrator or something? You'll have to check with where you downloaded it from.

ForumID can be found in the Forum Editor in the AdminCP.

Forum Relative Path, I presume is the directory path from the vBrigde to the vBulletin. Like './forums' or something.

Database Prefix is the table prefixes I presume (you can find it in your config.php file, if you don't know it already).

You'll need to confirm this with ever you downloaded vBridge from as I'm just giving you educated guesses
