First get a Chimchar obviously. When you evolve it into Infernape have it learn close combat.
To get flamethrower, have infernape learn it as a Chimchar at level 41 or get the tm for flamethrower in the fuego ironworks.
You can get fire blast at the city with Maylene. It's in the department store.
You can get brick break in the Oreburgh gate. You need the bicycle, and I think you also need surf. (I prefer mach punch instead of brick break, but it's up to you)
Hope I helped!
