Yes, there are tests for each class. (Tech, General, Extra). Tech is the first and gives you 2m/440. It also gives you CW (morse code) on other bands. General is what most people get, gives you voice on all bands. Extra gives you a little wider frequency range on the lower bands.
I used these study guides to get mine. Having an electronics background, I found the tests amazingly easy.

The AARL site also has lots of good information.
This is a practice test site:

An 85' tower would work quite nicely. LMR400? Thats good coax and will work great. Same for the PL259 plugs. I don't know anything about the IMAX 2000, but yes, you would need an antenna that is made for the frequency you wish to transmit on.
That is what a lot of people start out with. One you pass the first test, Tech, you can talk on 2m/440. With all the repeaters around, 2m/440 has quite a range. With an 85' tower, unless you're blocked by a mountain, you would have pretty decent performance without the repeaters, as well as being able to hit repeaters a long way away. (With a decent antenna on your tower of course)
Great info GunNut! Thanks for asking the question SOCOM! Getting my Tech license is on my to do list - to be completed by Dec 2010.
