for the best start in firered first pick charamander and when you get to vermillion catch a pidgey etc then trade over your charamander.after this start a new game and repeat this for squirtle. when you start a new game with bulbasaur trade the other two back over. if you train them up evenly there is no need to catch other pokemon like your rival as you will already have a great team. email me if this helps.
