Sorry, I don't follow why you cannot get past Step 2 - the first five steps are file edits, steps 2 & 3 edit the same file !
FYI : It doesn't really matter where the chat is installed, relative to the forum, as long as the [relative] path to the vB config file is set correctly in the CMS file. By default, it assumes that the /chat folder is in the same parent folder as /includes /admincp etc, which it appears to be in your case.
