Not sure whether this has been mentioned so far but also make sure after you're safely down on three points (after landing) that you keep the stick fully back during the rollout and this gives you more directional control.
My dad, Hector, who was an experienced instructor on type always insisted on this - I know as I learned to fly on the Chipmunk which is a fine flying machine, even in a crosswind.
That said once she starts to groundloop you have to be quick to stop it - I recall a landing after my second solo having just "relaxed" after what I thought was a super smooth landing. Being the good training machine she is/was I was taught a salutary lesson not to relax until down to taxi speed!
