To start, just give the back area a quick rinse to remove any large amounts of dirt
Tape off with blue painters tape the upper part of where you are painting. Basically run a piece of tape right by where the key hole and 3rd brake light is, so you dont' sand too high up.

Then take sand paper and a bowl of water, wet the sand paper, then start sanding the area you are going to paint. Rinse the sand paper occasionally to get the most life out of it. Sand until the clear coat(shine) is gone, and the sand paper is turning the color of your car.

Now wipe that area down with a dry cloat, until it is 100% dry.

Tape off the whole back end of the car with newspaper, and painters tape. Also be sure to tape off the licence plate lights, wouldn't want to be painting those.

Now shake the can of paint up well. Follow the directions on the can for how to spray it onto the car. Probably will need 3 good coats. After it dries for 30mins - 1 hour, apply the clear coat. Do 2-3 of these. Let dry for another 1 hour. Remove tape and newspaper slowly and carefully, so you dont' damage the edges of the paint. Wait 10~ mins or so between coats.

All done, good job!

I too was scared painting something on my car for fear of totally screwing it up, but if you take your time and follow what i said you can do it just fine.
