i agree with everything freebase dali just said.

as far as reading music, sheet music for kit drumming is pretty basic and shouldn't take anyone that long to pick up on. it will feel weird and you might play the lines in a stuttered or choppy manner when you start, but with practice you'll eventually be able to read and play as though you were reading words and speaking them aloud. it's something which could be viewed as not completely necessary as not a lot of bands use scored music, but to be proficient at it is to be that much more in tune with how your instrument functions out of and within an ensemble of any kind.

it can also be a valuable creative tool in the sense that if you have something that is technically beyond your current reach and the complexity of it has something to do with your inability to overcome it, then the ability to visualize it in a linear manner or even write it down will give you mental reference points and even further your facility to slow it down.
