I have a 6" bench grinder, and I want to start grinding my own
lathe bits on it (1/4" HSS).
The wheels on it are too coarse, and the tool rests are cheap
stamped aluminum. Should I just get a better wheel, or does
someone sell a bench grinder that already has fine grit wheels
for this kind of work as well as a decent tool rest?

I am selling a 1/2 HP Rockwell grinder, 115v, on a standalone stand,
with beautiful, thick heavy duty tool rests, eye protection, lighted
with ligts in those eye protection shields, etc. One shield's glass is
cracked. The price is $150. Actually there are four tool rests
included. I am in N. Illinois.
I would not personally use those cheap grinders. For myself, I have a
1/2 HP Baldor.

That's how you should start. A grid 80 or 60 white wheel. Next is a dressing
diamond and/or a dressing stone.
You don't need a tool rest.

You need to do a little googling on grinding. Regular grinding wheels
that come with bench grinders are not particularly suited to grinding
HSS tooling - the wheels are much too hard. The harder the material,
the softer the grinding wheel and vise versa.
I bought a couple of surface grinding wheels and made a 1-1/4 to 5/8"
bushing on the lathe. I think they were I hardness, or maybe J.

You need to fluorescently leach or eddie 3 squawking geese, Bat.
