Video Editing Software (and some fraps help)

[Aerozord]

Anyone know of any good ones? I want something that isn't too hard to learn as I am fairly new to it as a whole. I am ok with paying for it as I will probably use it for commercial use not too far down the road. Obviously would also like it if audio editing is in there too.

On a semi-related note. Short term I'm using it with fraps to edit game recordings but ran into two issues. First is the video is abit too dark, and sound is abit too low, despite both being at reasonable levels when I recorded. Any ideas on how to fix this besides cranking them up when recording? Which I want to avoid because not only would it make play less enjoyable, but worried about feedback when I use a mic
