Removing dents from oil pan

Thanks to a fellow FABO member I finally found my early A body slant 6 oil pan. It has some bumps and bruises on the bottom of the sump area and I’m looking for advice on how to fix it.

I just bought my first(cheap) hammer and dolly set, and I have a gas torch to heat the metal up and make it easier to work. Does that sound ok? Metal shaping is totally new to me so I am open to suggestions.
