Mount the vise and the grinder on the ends of the bench top.
You want as much uninterupted bench top space as possible.
And if you're going to go with a metal vise, get one with
an anvil - that's handy.

From the picture the OP referenced, the metal working vise appears to be
one that has a swivel base. I would further emphasize charlie b's advice
that the vise should be mounted at the end of the bench. There are times
when swiveling it 90 degrees is real handy.
