Need to replace my Evo

[Sheik_Yerbutay]

I need to return my Evo to BB due to a buzzing earspeaker thats driving me nuts. My question is, I am currently running Fresh's latest ROM and have backed up both the Nand + ext and the google proprietary files to my sd card. Will I need to root the new phone and install all of the apps or will a simple restore of the aforementioned backup files work?

Also, should I try to wipe my phone before taking it back?

Thanks in advance!
