Yes, this is the recommended method to update with the joey and speedrabbit kernels. Just follow the tut using the speedrabbit tar file instead of the zefie file and it will work. I'm currently using speedrabbit's 1.6 kernel and didn't even know 1.7 was out, so i'll be flashing using this method today as well. As far as moving the original sprint file from the binary folder, most say it is better to remove the file from the folder completely(doesn't matter if you rename the file or not if you do), but I've flashed my phone twice leaving the file in the folder and just renaming it. No problems both times. So it is really up to you. Both ways will work just fine.
