P-train,
I'm not certain what part of the country you live in, other than the southeast - that info might affect my advice. I would probably want more excavated than 2 1/2", with a thicker base. For a meandering path like that you should be able to follow the existing grade, so long as that does not mean that the walk is pitched toward a structure (hard to tell due to the perspective of the photo). I'd want much tighter joints than what are in the photo. As for steps - maybe my eyes are going on me - I don't see any steps, so I can't advise you one way or another.
For joints - listen to Penn. One thing we tried recently is to blow out the joints between the flagstone with a leaf blower to create more of a crevasse, then fill it with polymeric sand. The thought is a thicker bead of poly sand is more likely to hold together than a thin dusting.
