use a masterball.
Find the crystal onix, make it weak and catch it with your best ball
"I want to be the very best, Like no one ever was, To catch them is my real test, To train them is my cause..." I believe that sums up what you do after beating red
There is no best Pokemon to catch, as you train each individually.

I'm guessing you have the Nintendo: the best game for the Nintendo is Pokemon Platinum because you can catch all the lengendary Pokemon and it has surprises in it. If you have the Gameboy Advance I recommend Pokemon Emerald or Pokemon FireRed. I like Emerald because you can catch Latios and Latias (i think i spelled there names wrong sorry they're psychic and flying type). I like FireRed because you can catch Mewtwo and Mew. Now if you have the first version of Gameboy you soon play Crystal.
in Pokemon crystal the best Pokemon to have are feraligator(evolved form of totodile), weepinbell, kadabra, ledian (i would advise you to this Pokemon ice punch and headbutt), and pidgeot. these are the Pokemon i beat the elite four with
