Do I want Cyberlink DVD if I am just burning photo's on to DVD?

I merely use the Nero burning rom on my lite-on DVD burner and only use it to put photo's on DVD and don't use Cyberlink DVD.

not really. if you're using Nero consequently there's not much point to have it taking up easier said than done disk space
no you can use any burning prog, i use nero burning rom also
