Gunfighter,
I have not used Uncle Mike's rubber grips. I plan to order some very soon. I have been using Hogue wrap around that I don't consider confortable.
For the steel guide rod, I would urge you to contact CZ-USA. I don't think it is needed in the 9mm. If you do get one, you will need to modify the slide.
I am using factory Tanfoglio and CZ magazines. They work fine. Some members of this forum have indicated that small adjustments need to be made on some aftermarket magazines made for Tanfoglio firearms.
I do not know about the slide.
As for the conversion to DA/SA. I have never heard any reports of it being done. Several reports on this forum of converting to SA. A call or e-mail to CZ-USA might be a good idea. 1-800-955-4486 or gunsmith@cz-usa.com

How would Tanfoglio pistols rate in comparison to the CZ line-up?
Second.

Seriously, I don't own a EAA/Witness to make a detailed comparison. I have had opportunities to shoot them, and they were good shooters. I have heard complaints about EAA support, but again no firsthand experience.
As for reloads, I have been shooting reloads in both of my CZ75SA's without any problems. I use a Dillon progressive to make enough for my IDPA and IPSC shooting.
Shoot safe, and have fun!
