Sorry to be a pain but, is there anything I need to know when running at&t 2.0 update? I heard there may be some extra steps. CanI still use the all in one Toolkit? I'm getting ready to take the leap. I'm giving at&t to the end of the month for the official JB release. Also with 2.0 do I need to do anything differently before adding Viper?

To be honest, you should just unlock and flash. Once the update comes out, it will patch the exploit and you won't be able to unlock and root for a very long time.
As far as being on 2.20, I was as well and the toolkit worked great..and yes with the majority of Roms, you have to flash the boot.img of the rom before flashing it in recovery (TWRP). The way I do this, is using flash gui app - flash the rom.zip in that app, reboot to recovery, wipe (factory reset) then install the rom
For viper, they use an installer that wipes and flashes the boot.img for you. Another great thing about viper!
