OK. Rebooted my system again and now ADB recognizes the phone when on and in fastboot. Go figure. Since I have ADB working now, do I need the fastboot/adb zip listed in the OP? If not, do I just place the images in my c:\android-sdk-windows\tools folder? Edit: It looks like c:\android-sdk-windows\platform-tools contains some of the same files as the fastboot/adb.zip. Guess I'll try there. I assume I have to direct the command prompt there before pushing the files in fastboot?
