[dba-Tech] Home Network Setup

This may strike you as odd, but even though I've been in the business for
30ish years, I have never set up a network, not even a home network. And
now, for the first time, I have two computers at home and running, so it's
time to take the leap.

On box, my faithful old tower, runs Windows 7 and has been declared a part
of a workgroup called Camelot. The other, a fancy new laptop, has so far
not been declared - principally because I can't find where to do so in the
Windows 8 UI.

Both computers are connected to a wireless router. My sole printer (a
Brother MFC-J625-DW) is connected to the Windows 7 tower, but it allegedly
can do wireless as well. I'll have to dig up the manual to see how that is
done. Anyway, the goal is to have the computers able to see other other's
files, and in particular the pair of USB external drives, which at the
moment are connected to the tower.

My questions:
1. How do I declare the Windows 8 laptop to be part of the Camelot?
 workgroup?
2. Once that is achieved, are there any extra steps I must carry out to
make the machines visible to one another?
3. I'm OK with skipping the wireless printer connection, since the only
time I'll ever be moving it is if I move out of my apartment. But I do want
the printer to be visible to the laptop. How do I do that?

TIA,
