As far as OTA programing goes you have to use a non EVDO prl and OTA in 1x. This will allow the phone to download the EVDO prl for your market and update it on your phone. Once this is done you should be able to OTA using the EVDO prl that was updated when you did OTA if you ever need to in the future.
Ok for the USB problem you need to have the HTC drivers loaded on your computer.
