Enjoy your Royal Flush, and like everyone here says. Guessing it won't be lonely long. My RF is actually for sale, as one of the really difficult parts of this hobby is having to make cuts in the line up for new games. Sounds like you are getting good advice, and have the skills to follow instructions. To answer one of your questions, on this site it is generally "Pinsiders". Otherwise, just fellow pin hobbyists, or addicts.
The two most important pieces of advice from all above. Keep good carnuba wax on the playfield, and replace balls as soon as they look the slightest bit worn.
Enjoy.
