I've read through a few of the threads about DIY changing of the plugs, my car is at 61k and it says it need new plugs.

I'm pretty capable of doing such things usually I just wondered if there is anything specific I need to know before I attack the car! Is there any order they need to be done in, are there any hard ones to get to like in the V8, is there a manuel on line anywhere etc?

Any help would be greatly appreciated.
