Giulietta I'm drooling over your boat and traveling genny cars.
No-one's mentioned that your head sail and main work together yet, just to make matters more complicated... ;P To see this play around as sailorman mentioned, but then once you have a handle on it start adjusting the main as well , experimenting with different traveler positions, etc. Watch the genny change shape...
I personally find the Annapolis book of Seamanship's section on sail trim (chapter 3) to be a good basic introduction.
An excellent exercise in general is to learn to sail your boat 'rudderless'. Lash it to the center of the boat and use just your sail trim to steer.
Try to sail someplace complicated this way.
Ok, now you will be busy all summer just sailing in circles. hahahahaha.
