Eric,
Sail the boat before making any changes. Learn the boat as is before making any changes. Get your crew trained and learn to dance with them. Giving the crew the main traveller control is a nice "go fast" but only after they know how to trim the mainsail/traveller car in concert with how you steer sailing to windward and on a reach. The biggest improvement you can make in boatspeed is "learn to sail this boat". At this point in time, it is well under rated in PN so have fun while it is easy and get better fast.
