a couple of things in no specific order
the grizzly mini-mill is the same one that you can get from homier and harbor-freight. the main difference is the cost, the other difference is the color and the collet included, besides that there really is no difference. so save yourself some $$$ and dont buy the grizzly one and get either the homier mini-mill
homier mini mill
or the one from harbor freight, i cant find it on thier site right now but i know they have them in thier stores, and online too, just not sure where :P
as for the vertical ballscrew, i would suggest rockford ballscrew. give them a call, tell them what you need. you will need the screw and a nut (2 nuts if you want to do it better to stop backlash) anyway click on the about us there and either call them up or e-mail them and they should be able to help you out.
hope that helps out some.

Going back to the z axis mod. Can you tell me the model and the spec of the ball screw and ball nut that you use? A few close up pictures of the ball nut mount would be nice.
I found a website selling Grizzly mill CNC conversion plan for $50.
