The easiest way to root the phone is to use the stock fj12 Odin one click rooted package in the other thread. It with get you rooted but you will not have a custom recovery.
A custom recovery is required to perform the nandroid backup. And on this phone the only way to get a custom recovery is to flash a kernel with the recovery built in( yeah I'm not happy about it either) but agat has several stock kernels with recoveries packed in called repack kernels like the one here in this thread. Then if you want to go the custom kernel route with new features you can download agats custom kernel for the epic 4g touch or the kuban kernel for the epic 4g touch which is what I am using.
All of them have similar kernels that should be compatible with backups made from different ones!
And if you ever get your phone to where it can't boot, as long as you can get into Odin/download mode (volume down + power button) you can flash the stock fj12 Odin one click package to get back to complete stock!! Pretty nice fail safe!
