The world has changed over the past few years with advancements in tools like Camera Raw and Lightroom. If you are taking the path of doing virtual / non-destructive image editing in the raw converter then you want to do as there as possible and as little as possible in Photoshop.
Sharpening needs to done at least twice, once as input sharpening (which all digital images need to one extent or another) and the second time as output sharpening, which varies depending on the device, ie: web or print, glossy or matte, etc.
So doing input sharpening in the raw converter makes sense and then doing your output sharpening in Photoshop (if that's where you print from).
The sharpening tool in Lightroom is very powerful. If you want a highly automated sharpening workflow look at Photokit Sharpener, an automation plug-in for Photoshop. With this you want to turn sharpening off in Lightroom.
Many choices. There is no one correct path. And yes, Vibrance is a form of local contrast enhancement, similar to sharpening, but not the same. Worth experimenting with.
