Basically RA4 processing when you get the hang of it is actually a doddle. It is a balancing act between temperiture - exposure-color-balance-film-printing paper-and chemicals.

Get one set of materials that suits you and stick with them. Get one set of chemicals to process the film and one set to develop the paper and stick with them. Make sure your temperiture is consistent and the remainder will come naturally. You can 'dodge and burn' in the same fashion as B&W but you run the risk of odd areas with different colour balance. It is all a matter of practice. That $60 fee to teach you looks like a good deal. There is nothing like someone to show you the ropes
