(I've only installed the AT version, but I'm sure the PC version is
similar.)

The Inboard 386 plugs into a 16-bit slot in your AT.  The 80286 in your 
computer is unplugged, and a flex cable is plugged into the board and the
80286 socket.  An 80287, if present, is removed, but there is a socket on
the Inboard for an 80387.  Note that you'll need to purchase a different
installation kit (cable & other goodies) depending upon what kind of
80286 socket you have in your system (PGA, PLCC, etc.)

It's tricker to install than just a board, but the instructions that come
with it are very well written and illustrated.  With the exception of the
screwdriver to open the computer, all of the tools (chip pullers, etc.)
that you will need come as part of the kit.  After installation, you
have to be a little bit careful when you open the computer, because of
the flex cable running through there.

I don't believe so.  The Inboard 386/PC is designed to plug into an 8088
socket.  The Inboard 386/AT is designed to plug into an 80286 socket.

Disclaimer: I'm speaking as someone who has installed a lot of Inboards,
but definitely not as a representative of Intel.
