You can not your Pokemon all need to be lvl100.
Treecko evolves into Grovyle at level 16. Then, it evolves into Sceptile at level 36. Same goes for Torchic - Combusken - Blaziken and Mudkip - Marshtomp - Swampert.
Yes, infact it is, just keep training your Pokémon and get them as high a level as they can!

You can't get any of the Hoenn starters Sceptile (Treecko), Blaziken (Torchic), or Swampert (Mudkip) in FireRed/LeafGreen; you'd need to trade from Ruby/Sapphire/Emerald. If you do trade a Sceptile, Blaziken, or Swampert (or one of its previous forms) from RSE, you should probably mate that Pokémon with a Ditto in your RSE game first. After you hatch the egg in Ruby/Sapphire/Emerald, you can either trade that baby starter or the original higher-level Pokémon to your FireRed/LeafGreen. That way, you have one form of the starter in one game and another form of the same starter in the other game.
