You must use the steps for the Motorola Droid, they are near identical and the rooting steps are the same. I have the A854 (MTS Motorola Milestone)
Use a barcode scanner or google googles, install "Universal Androot" This is the tool I used. If it can root your phone it will, if not it will not harm it.
That's it as far as rooting goes. Your next step is to download "rom manager" by clockwork. Then pick a rom out of here Droid - ROMs - Android Forums
Save it to your sd card, no extraction necessary, and use rom manager to install rom from zip
Post any questions or concerns about the steps and mention how it goes
