Hiking between Merced and Vogelsang HSC’s

I'm going to be going from Merced Lake to Vogelsang HSC next week. There's two trails, both about pretty close in length. One follows Fletcher Creek, the other Lewis Creek. Has anyone done either of these trails and could tell me about them (steepness, scenery, etc)?

Also, camp at Vogelsang lake at a distance from the HSC, or at Fletcher Creek at the backpackers campground? I'll have my bear cannister for flexibility so the bear boxes are irrelevant.
