I sincerely wish you "Good luck" with that, Darrin! I've found that going through other people's flash source/actionscript can be pretty confusing sometimes, even for an experienced flash developer. Since you mentioned that you bought the template, have you considered contacting the template's author and inquiring about how to make the changes you need?
He should be able to point out what needs to be done, and it shouldn't be that difficult. He may even be willing to make the changes for you for a small additional fee.
I'm not trying to scare up business for him; I'm just thinking out loud about the quickest/cheapest way to get what you want working the way you want it to.
