Sorry but, are you looking to make straight copies?
As for the distro, that's a really tough one as many will have different opinions. What I suggest is you try some of the user friendly 'Live discs' ie knoppix though I think Kubuntu comes on a live disc as well. These run direct from cd, so nothing gets installed on hard drive etc, thus you can get a feel for linux and then look around and make your own choice on distro. Kubuntu for what it's worth comes as both live and installable so if you like it install is an easy option.
P.S. if this hasn't helped post back and say so, I'm sure others will endeavour to help.
