You hardly need a "course" for a taildragger, just a bit of practice with an instructor, or just someone who knows how. There's nothing special about it, just a slightly different technique for t/o and landing.
Yes, and I have flown with a few pilots who have learnt that way or learnt with instructors that have learnt that way, can be quite frightening and many have not been taught wheeler landings. As Pilot DAR says, there are many types that do need treating in their own way, so ideally learn initially on a "generic" Tailwheel that all techniques can be practiced on.
As for farmstrips, again, if you learn PROPERLY, you will learn a lot more about possible hazards - many farm strips have much more involved than just being short!
