Just pull up the spark plug wires. (Pull straight up). They go straight down the valve cover.

Answer 2

I don't think you should be removing spark plug cables if you need to ask such a question. You will damage the cables if you pull them from anywhere except the boot. Let someone who has learned mechanics work on your car. If you want, you can learn mechanics too, go to your local college and take a night school course on mechanic basics.
