Most of the DV camcorders are now able to take fairly to very good stills. Most of the newer ones tend to have firewire for video and use USB or removeable media for stills (ie smatmedia, compact flash etc.)
As for software, I do not know what you will get with the cam, but it will be enough to at least get the pics onto the PC if useing USB or you will need a card reader if useing removeable media. Getting the pic into the editing software is just a matter of opening the software and openiong your pic from there.
I would not think you would get all the software included with the cam as after all it will mainly be designed for video use and therefore purchase of additional software stills software is almost certainly required

. You would be more likely to get all this with a dedicated digital stills camera.
