First of all, say it with me, PARAGRAPHS. You will get a much better response from people without the wall of text
I was in a similar position to you when I first bought my GTR. A lot of people recommend buying already modified examples as you can save a shitload of money etc but I never really trusted anything that had any decent work done to it. And like yourself I had planned on using mine as a daily drive. Having a 300kw + car for a daily drive just isn't necessary add in the fact that most of the modified examples are running twin plate clutches etc that can be a pain in traffic I concentrated more on finding a clean stock example rather than the one with the most mods.
Try and get a later model 32 if you can. 94 Models use the same crank as the R33 with the bigger oil pump drive so you can be a little more confident in it surviving a few track days. Also if you can find one with the stock turbos replaced with similar sized units that would be a benefit as the ceramic exhaust wheels are getting old now and tend to exit stage left with anything over a bar of boost.
Make sure you do all the usual checks, steering wheel and pedal condition will normally give you a good indication of kms travelled. Most of them won't have their stock dashes in anymore but few people change the pedal rubbers.
Hopefully a few of the other more experienced guys will throw in their 2 cents aswell.
