The timing chain should be replaced simply because it wears out. Might as well do it when you swap the cam since you're in there already. Same goes for lifters. A dual roller chain is the way to go; less stretching problems than a single row chain. I wouldn't install gears if I was you. They are noisy, expensive and are not that important unless you're planning to run at high rev's all the time.
