When editing my video i first did a rough edit in microsoft movie maker so i knew what order to do the clips:

(again must state that you will have to click on the images because Reallifelog wont show my images for some reason)

Here is an image of my video being edited in windows movie maker:

Even though WMM isnt amazing it is usefull for rough work and placing rough titles in aswell so you can build up a good idea of how to fine edit your video.

Heres the video inside Avid:

With both programs there are certain things that help more.

Windows movie maker has an easier interface to use compared to Avid because everything is word based instead of having icons.
Windows movie maker actually has some good title animations aswell if you use the proper text.

Avid has alot more options and once learnt is easy to use.
It gives you two windows to see your main video and stuff you can edit into it.

How i edited the video was making a first cut and then took it into avid and cut it from there, a tool in avid lets you trim a few seconds off when needed and this is a video only alloweod ten second of actual footage so it helped alot.
My first edit was about 15 seconds long but i got it cut so easily.
