I was going to follow the FAR guidelines for the Baxter launcher,
placing one at the CG and one at the aft end of the body. I've seen
other references that suggest one at the CG and one at the CP. The skin
is very thin (0.016 inches) so I'm going to have to add stiffeners
underneath.
I'd really like to 3D print the rail guides out of nylon but I'm worried
the steel rail will cut through it so I'll make them out of aluminum.

IIRC you are using a long rail, which should reduce weathercocking to a certain extent. Longer rails means higher off-rail speed, which means that even in a wind gust your relative wind will shift by less degrees off the nose.
Also a controversial topic, but where are your rail buttons going to be? That can greatly affect off-rail weathercocking. Placing the aft button close to the CP can reduce the swing somewhat.
