When taking out the Torah from the ark, what is the proper procedure in these areas?

• On Shabbat, the Chazan faces the cong. (back to the ark) when saying Shema and Echad Elokeinu. Then he turns to face the ark to say Gadlu and turns again to walk off the bimah. In which direction should he turn - clockwise or counter-clockwise?
• When walking from the ark to the Torah table, which side of the shul should he walk? To his right or left?

Sources for both, please.
