Help does the nikon d3000 and d3100 have the same Lens?

Do they both come with the 18-55mm one?

is this image quality ANY different?

It's the same with Canon, which I have, every dslr comes with the same lens.

Image quality, probably no different. I have a Rebel XS at 10mp and a t1i at 15mp. There's not much difference until you magnify the shots or make very large prints. The reason I have the t1i is for the video.

There's no difference in the kit lens. Both have the same 18-55mm Lens.
There would be a little better image quality in Nikon D3100 as it has 14MP CMOS sensor while Nikon D3000 has 10MP CCD sensor. Other than this difference, Nikon D3100 has 1080p video recording (which doesn't make much difference in DSLR's).
