Not entirely sure what you're looking for, sorry.
There are a variety of editing programs available in the free to $300 range that can be used for basic editing---premier elements, pinnacle 16, sony vegas...
The free Cineform software from GoPro is used to trim clips and do some color/exposure correction and, if you're doing 3D like me, to combine the left and right clips into 3D clips.
Beyond that, video editing is...and my appologies if this is more basic than you're looking for...a matter of selecting and trimming the clips to length, arranging them in the order you like, creating transitions between them, adding titles and sound.
The editing programs I've worked with have an area of the screen that displays/lists the clips availble for use in your video, one or two preview pane where you can watch either the clips or the video you are working on, and a time-line area.
My work flow consists of
(extra 3D step: combine the left and right clips into 3D clips in cineform and adjust their vertical alignment---cineform often gets the vertical alignment wrong)
editing the length of the clips---either in one of the preview modes or by dragging the clip to the time line and trimming it there. If you are shooting continuously you have to break the continuous clip into smaller ones---the software I use (Pinnacle 16) has a utility that does this automatically splitting it into shorter clios of user specified length)
place the trimmed clips in order in the time line---basically a drag and drop.
defining the transition between the clips (optional if an abrupt change is acceptable). I mostly just use a simple cross fade---first clip fades out while the second fades in.
Once I have a rough cut of the clips in order I watch it and edit ruthlessly to bring the total length to the 4 to 6 minute length---sometimes the hardest thing to do.
When I'm done with the video I record some music (most folks use royalty free music that comes with the software or is available on line) and add it on a separate time line.
Finally I add titles. I make a point to explicitely say it's me playing the music in the end titles 'cause someone made a copywrite challenge to one of my recordings that was resolved when I pointed out it was me.
Some folks also add text or talk over to point out interesting things during the video.
When this is all done, export to an MP4 and up load to you tube. You tube has some editing tools, and a stabilizer that one of my friends swears by. If you use their stabilizer you have to add the titles after the fact in you tube or they will bounce arround.
