I Need A Software Tip

So I have a master dvd of the band shows I did on the 8th of May. First off, this is my material, my band, I paid for the filming, editing and master videos. I wrote the songs , and the cover material will be paid for as far as royalty rights to include on the dvd. So no piracy issues.

Ineed to be able to

A: Rip the dvd so I can burn more. (I have a DVDRW and my new computer has the juice for these tasks.)
B: Edit the dvd to cull out a 5 or 6 minute trailer dvd.
C: Capture stills from the dvd
D: It is curently 1 long file and I need to break it down into tracks.
E: Be able to post video images to various sites.

What software is available for this... and although I know it's a tall order does anyone know of any freeware that will accomplish this?

I can probably get the original files from the guy who did the dvd and dump them onto an external hard drive.

Any help greatly appreciated.
