Use a spark plug socket to take them out, as the rubber donut in the socket will grab the plug and allow you to pull it out.
Buy about a foot of vacuum line, and slip one end over the top of the plug. This will allow you to feed the plug down into the head, then twist the line to get the plug started. Once the threads have started the plug will stay in place enough for you to pull the vacuum line off.
Done, and much easier. Oh, you did remember the anti-seize on the plug threads so it is easier next time. Right?
