If the original poster is still not experienced enough to adequately care for a Coastal, then I feel that Londos1990's suggestion to hold off on purchasing an Olive is quite wise. A large Olive python can be a handful for even an experienced keeper, and it is a very good idea for dylanthomas to get things right with his Coastal and do some proper research before purchasing another animal.
Oh, and as for that learning curve you mentioned - you don't just purchase an animal with zero prior knowledge or research and just hope you learn it all as you go.
