That looks about right.
Make your in SPRecovery before you start typing the commands in adb. From there you should be able to load your ROM of choice.
And MAKE SURE!!!... you put the raw Nandroid restore of the ROM you want in the Nandroid directory BEFORE you start the process.... otherwise you'll be stuck high and dry re-flashing whatever your have in your Nand directory. I always keep 2 or 3 full nands of my favorite up to date builds in my nand dir. Just in case..
