If it were me I would give consideration to doing the north side first and then dropping into the glen to camp before accessing the south side.
My reasoning is that doing it the way you propose, the path up to Bealach an Lapain is very steep and will be hard work with a pack, whereas IMO if you came down that way the hills on the south will be easier to access, in particular a path not far down the glen to Kinlochourn gives easy access to the end of the south ridge.
