Don't think you need a 4x4.
I don't know what kind of preparation you need for the Chilkoot. As with every hike, the weather makes a difference. And yes, the amount of people. Cottonwood less people, maybe none or a Mountainbiker here and there (or with bad? luck a group just starts with you). Easy hiking. You are more on your own. Maybe a little pathfinding in places, but nothing serious. Vice versa I also wouldn't say the Chilkoot prepares for Kluane. Maybe Bock's Lake is not a bad introduction or: sounds like the most difficult to me. ;-)
