The only "passes" that I can recall from Pokemon FireRed are the Tri-Pass, which grants you access to Islands One, Two, and Three, and the Rainbow Pass, which grants you access to Islands One through Seven (the Sevii Islands).
There are 150 Pokemon, 1-150 are found in Fire Red and Leaf Green as well as future games.
every where
Pokemon's 1-384
Yes
Catch all the Pokemon!
u can get all of them...
You have to trade and catch as much Pokemon as you can
all over
YES
By trading and catching them i think
you have to trade them from other Pokemon games
Not at all because firered has a few extras in the game it has Pokemon that red couldn't get like delibird, sentret and natu.
