Right. It really isn't that bad. One problem you can run into, just for future reference, is that if the plug wires are really old, they can rot around the plug, so when you pull out the plug wire a big chunk of the rubber that surrounds the plug stays inside the hole.
Obviously that is an inconvenience, but it's a real problem if you do manage to get the plug out without removing all that rubber first. Little peices of rubber are not good for your combustion chambers. You can get the pieces out with the broken plug wire, after you put a little glue on the end to pull the broken bits back out.
Just a little food for thought.
