I'm a bit surprised the elevator position is still bad. I spent quite a bit of time trying to eke out every pixel. Anyway, here are some things. I know you probably have most, if not all, of these addresses anyway, but just in case.

0785 is the memory address for if you do/do not have the candle. If you poke the value to 1 with a cheat, you can just have the candle. IIRC this affects the way the invisible moas move later on for some reason, but other than that you can just leave it on or turn it off with no ill effects.
I thought I had Pasky's hitbox viewer, but I guess not. I'll get in touch with him.
