You want to have the bars comfortable when you are in what's called the attack position. This means slightly standing, elbows out. Easiest and most likely change to make at this point is to rotate them for a better fit for you. Once you get them in a comfortable place you will likely want to adjust the clutch and brake levers, which is easy to do by loosening the clutch perch and brake master cylinder, rotating, then retightening them all snug.
A key thing if you loosen those fork tube clamp bolts is to not overtighten them as that would hurt the fork internals. The torque spec is generally around 18 foot pounds, so just snug. If you haven't gotten one yet a factory shop manual is a very good idea, as is Eric Gorr's book on Offroad Motorcycle maintenance and performance.
