Just start with basic quarter note strokes, then go to double stroke. Parradiddles for chops and stick control. learn the standard 3,5,7,9,11 yada yada stroke rolls. Those are all good for chops. Other than that start playing to simple songs. Since you already know cause you're a musician, Practice and persistence is a huge part. Once you get the feel down for playing to a song, start putting in fills and improv.
Oh and also play with a metronome as much as possible. A drummer with no sense of timing or cant hold a tempo isn't a very useful drummer D: I felt obligated to say that
