Muskie - good questions. I'll try to cover them all.
There is no such thing as a company-specific RC. As Bob mentioned, some people will call certain cards their first card of that company like a FTC (first Topps card) or a FDC (first Donruss card). We have decided on this site that marking cards as such is not needed.
Losing Rookie status in MLB for winning ROY is based on games played, but that has nothing to do with RCs in the hobby.
Rules for what constitutes a Rookie Card changed in 2006. What we're talking about here is pre-rule change. Bowman was considered a major release, and if a player was included in Bowman, it was a RC. That is not the case any more, as Bowman now has the Prospects sets which are not considered for RCs. So before 2006 and after 2006 are different animals. Also, we now have the companies using the little RC shields on the cards that can be considerd RCs. (Although, they also include them on the parallels, and they are not RCs.)
There is now a difference between First Card and Rookie Card, mostly because of Draft/Prospect sets.
If for some strange reason a player plays for 4 years and doesn't have ANY cards, and then has a card in year 5, they would be considered the RCs. That was actually the case for several players when Bowman hit the scene in 1948.
More recent was the case of Kevin McReynolds. He was in 1984 Donruss and Fleer - both are his RCs. He also only appered in Donruss and Fleer the next TWO years (1985 and 1986). He FINALLY appears in a Topps set in the 1987 Topps Traded set. Many people back then were trying to get that card because of it being his FTC. It was all contractural, but Topps missed out on having a Kevin McReynolds RC.
