Quick ROM flashing question..

[sparky100]

I'm using a CDMA TP2 on Pageplus. I set it up with this as a general guideline: http://wiki.howardforums.com/index.php/Most_HTC_Devices

I want to upgrade from 6.1 to 6.5. If I flash a new ROM, am I going to have to re-enter all of my EPST programmings? Also, will my SPC change with the new ROM, and will I have to re-copy the DMU key using QPST?
