what team should i run for a fire red playthrough

Charmander makes the first two gyms rough, so the early catches are what fix it. Grab a Pikachu in Viridian Forest for Misty, and either a Mankey or a Nidoran that you level until it learns Double Kick, for Brock. After that a Lapras (you get it free in Silph Co.), a Snorlax, and a Gyarados raised from the Magikarp you can buy will cover pretty much everything. Throw in something with Psychic moves and the Elite Four isn't much of a grind.
