All -
Thanks for the replies.

The "tower" will be approx. 20' tall and the tallest antenna is approx. 10.5'.
The support structure will be set in a concrete base that is 4' deep x 4' long x 2' wide. The engineer will tell me if I need to rebar it (which I think it will need to be). It will also have a support tied into the rafters of the roof for stability at approx. 8' height.
I will be running LMR 400 coax cable to the antennas, with each having a lightning suppressor.
I have some leftover EMT, so was wondering if I could use that, but as resqcapt19 points out, it has to be "pipe" and not "tubing". I knew I had read "soething" about using 3/4", and was thinking EMT was ok, but couldn't remember where I saw it (the little grey cells can only do so much at one time).
I was planning on driving two grounding rods, but not four. Perhaps splitting the difference and going for three would be ok.
It will also be tied in to the house ground system.
Thanks again for all the responses and help.
