You should be able to set Jon & Kate + 8 to a lower priority than your other recordings. Then if there is a conflict, the later recording will be used. However if there is not a conflict, the earlier recording will be recorded and this might interfere with you Live TV surfing .. If the latter happens often, you may simply have to use a manual recording.
I understand your pain, and in my case (being in California) I invariably get the first recording which is earlier than normal prime time shows. There is, unfortunately, no way to set up time blocks for either recording or to not allow recordings. Your best bet is to just record all the shows you like and watch them all from the DVR .. and delete the show after you've watched it .. but, we all watch TV differently, so it's hard to give you the perfect answer.
