In order to avoid having to use abd to push the su and superuser.apk I editted the update.zip of the 2.1 version of superuser to work with spr. I unrooted and gave it a shot just to be sure and it worked fine.So after you finish the sbf flash of SPRecovery then just put this update.zip in the root of your sd card then reboot into recovery. Go to install then press allow update.zip installation then install update.zip depreciated.After that you will have root access without using adb and without losing any data.
