you can save your money and just go to XDA-developers. There is 100 how to's and it is very easy. You don't need to back up anything to "root" your device either as it's just a one click process. As far as stability goes then you might want to wait a few more days/weeks as all ROM being created now are based off of Froyo 2.2 and there is no source for the Kernel so some things are still buggy. I myself haven't had a problem running any 2.2 Rom's though.

FYI: you don't need a custom ROM or root access to duplicate that homescreen. The program is called "launcherPro" and they have just installed a custom dock bar with custom icons...all of which can be downloaded free.
