From using the program, I think when they say enabled or disabled they mean the service, not the blocking. You're right it would be a good idea to clarify, better maybe to say "service enabled, servive disabled" I guess.

I keep mine all disabled most all the time, and use wi-fi when home or when it is available. It seems a rip-off to be forced into a data plan, in my opinion that should be the customer's choice, so MoDaCo has really helped be opening this aspect of the real potential here for our wizard devices.

I don't know what each of the 4 subcomponents does exactly. I just turn em all off or on. When I use any data on GPRS, the icon at the top of the screen is similar to a connected wi-fi with the 2 arrows but noticibly different in that it has a letter in a box (E if I remember right). I never need much data. email can be kept in sync for offline reading using builtin client for outlook, and I've added gmail. uses almost no data to sync a little if it has been done recently. for news reader I think pRSS Reader is one of the best and very configurable to user preferences and has offline web cache. I don't need much more data than that while I am not at home. Google maps for windows mobile has low overhead too, but I rarely use that on the go.
