The posters who have responded already have it right: Do you want to stay in the same vein or do you want to branch out and see what Miles was capable of? If you like Kind of Blue, and want to test the water gradually before you take any great leaps, then start branching out into albums from around that period before you get into the more esoteric fusion stuff. Some good possibilities:
Cookin'
Milestones
My Funny Valentine
Miles Smiles
Nefertiti
Then try the albums that show the move toward fusion and his introduction of more electronic instrumentation:
In A Silent Way
Bitches Brew
