I'm going to assume you mean "Pokemon Ruby" in your question. Anyway, to trade between Ruby and XD, you must beat Pokemon XD and defeat the champion in Ruby.
No, but you must get to a certain point in Pokemon Diamond to transfer Pokemon from Pokemon Ruby.
You can beat it with Ground type Pokemon or Fire type Pokemon easily.
Go to the Elite 4, and beat them.
you can beat the elite four and,travel around the Pokemon world and catch every kind of Pokemon you like
