All of that and no beds? LOL.
#1 I have tried #1 and yes bucks did rub it.
#2 I have never tried.
#3 I don't do the fancy brand name minerals, but I do have out a trace mineral block at an established location. Deer hit it pretty good. You should start seeing more activity in May thru July. If there are other sources though you may not get as much use.
I honestly believe that alot of this stuff works if and this is a big if it is in the right location where deer routinely visit and feel secure. I don't think any of these gimmicks actually pull deer in. I do think though that if you can maybe establish a scrape/rubbing post that you can maybe make deer coming thru that area perhaps travel a little closer to where you want them to be. If you have the stuff above in a poor location then they will likely get little use. The biggest advantage of the above is if you get almost all the deer in the area visiting them then you can get a good inventory of the bucks.
Traditions only last if you pass them down to your kids!
