Uhm, something of a problem with your direction - the text you have listed for some of the replacements seems to presume that the "Last Post By" mod is installed, as it speficially references database elements unique to that script. I tried installing the Alt Body Preview mod, and didn't have the Last Post By mod installed, and it wreaked all havoc and generated major mysql errors.
As a suggestion, either clean up the instructions to not list those please, or list the Last Post By mod as a pre-req.
