Script Modifications Needed

I need several script modifications for a script called Affiliate Master. The script modifications needed are: + Meta Tags for Pages: Title, description, keywords. + Ability to write information under each category. + Hack for Mod Rewrite (turn php to htm/html pages) and write htaccess file and make sure the setup works. + I currently upload info via datafeed (csv, txt, xml files). I would like to be able format product descriptions without all the sentences being clumped together. If there's a simple way to do this, I could use help with figuring out how or a quick simple hack. If this is too complicated, then I can save this for later but would prefer it to be done now if there's an easy way to fix this. Demo to the script I need modified is here: [login to view URL] If you need to take a look at some of the actual script, let me know and I can send it to you.
