Ice Beam at least is useful in Kanto because it is at Seafoam Islands. Thunderbolt at Cerulean Cave and Flamethrower at Route 28. outside of Mt. Silver.
Wouldn't this be dependent on what version of HGSS are you playing? JP versions contain slot machines and buyable coins.
Also, would it be possible for Quilava to get away with getting Fire Blast as early as Whitney? It's been a while since I last played HGSS, but assuming you're capable of amassing the 5.5k needed for the TM, Fire Blast Quilava can easily be your strongest attack for quite a while (aside from say, Technician Wing Attack Scyther)
