I have an 03 mustang gt manual with approximately 111,000 miles and my RPM gauge sometimes goes up and down after I crank it up. Does not do this all the time, but enough times to bother me. Does this sound like something to do with the fuel filter or it's component?

I'm not sure about the aftermarket parts, check with rockauto, they have a good selection of part suppliers. For instructions you might find a free manual here: http://bit.ly/autozone_repair_info or go to http://bit.ly/alldata_repair_manuals or http://bit.ly/mitchell_repair_manuals_online and get an online repair manual subscription.
