1. Not a problem at all, no need even to print a ticket or so. They won't ask you a thing, already the question "you are a tourist?" will be highly unusual from my experience.
(Plus, as a funny detail, the Macedonians still have fond memories of the 1980s when droves of Dutch tourists visited the country annually. If you are fond to read during your travels, read A. Den Doolaard's "De bruiloft der zeven zigeuners". This book from 1939 inspired thousands to travel to Macedonia before the wars in the 1990s halted tourism. There is even a statue of the guy in Ohrid!)
2. None whatsoever by public transport. They'll take the passports from each person in the bus, and after 5-10 minutes return it to the bus driver with a stamp in it. You won't even get off the bus. On a bus, the fastest it has taken for an entire bus to get across was 5 minutes - the slowest perhaps half an hour if there happens to be a queue of other buses.
Refugees are currently not allowed into Macedonia from Greece, so there is not so much of a crisis anymore with this inside the country. Those who might reach Macedonia, are more likely than not not to travel onwards to Serbia by train (or crossing illegally) - not by bus for sure. Anyway, should not be an issue at all during your travels.
