In general the Exsanguinate build is more difficult to play, because there are some traps you can fall into. I suggest you transition to the EP/AP build which is more friendly for newer players to the spec. Your gear is good enough to try it out and it should give you more flexibility to get a feeling for how to play the Elaborate planning part of the rotation.
Are you using any addons to track durations and cds for your abilities? If you are not I can suggest the addon Weak Auras and import EZO strings. Those are a good place to start with. They give a lot of information in an intuitive way that doesn't take up too much space on your screen.
