Jason....just practice a lot, and when your instructor lets you, do lots of crosswind practice. I used to love an hour or more of circuit after circuit..its such great practice, and if you progress through the commercial types, you may never have so much landing practice again!
I trained at an aerodrome almost famous for its crosswinds, and it stands me in good stead.
I even heard about a guy who used to routinely calculate the cross wind component from his crab angle and airspeed in early final, as a habbit!
