Kodachrome was relatively insensitive to expiration dates. Assuming that those rolls are less than a generation old or so, if you wanted to shoot it, that film is probably still good so long as it hasn't been baked.
Last I checked, you've got until December, longer if the chemical stocks last, to get it developed.

Velvia is E-6 process, aka: standard transparency/slide film, same as Ektachrome, any pro lab can do it, pretty much any small lab can send it out or you can mail it off yourself.

The secret of Kodachrome, I've been told, was that the film itself was three separate layers of black-and-white emulsion with filter layers, that responded according to the three basic colors. The color dyes themselves were added during the development process, which I've heard involved as many as fifteen different, tightly-controlled steps.

Yes. It's a silver halide film that only contains the dye couplers. When it's in your camera, it's black and white.
And it's only 14 steps, hence the developing process name "K-14"
