Upgrading Board w/ Store Hack

I tried posting this in the Store Hack thread but it keeps giving me an error. I am thinking maybe its too big or something *shrug*

So I hope its ok that I posted it here.

If I am upgrading my board from 2.2.6 to 2.2.8, to re-install the store hack I only have to do the file changes right? Since the templates were custom and the upgrade doesnt override those or customized templates I dont have to redo those unless I reverted any of them, right? Also, would I have to redo the queries?

Sorry for all the questions but this hack is a big part of my board and I want to make sure I don't overlook anything when upgrading so the point system and actions still work after upgrading.

Thanks to any help anyone can provide.

You only need to do the PHP code changes. You don't need to run the SQL Queries or re-add the templates.
