I'm sure this is going out late for your current visit, maybe some words
for your next:

1) contact the museum well beforehand regarding this, some do allow
photography (though not in all areas), some do allow tripods (usually not
on weekends or in designated areas), many do not allow commercial use of
your shots taken there without prior permission and usually some showing
of pro credits or some such formalities.
2) when a tripod/monopod is not allowed I've been successful using a
length of string tied around the lense (close to the body) or tied to a
detachable tripod head (better) ... it should be long enough that it'll
reach your feet easily - step on the string so it has enough tension to
keep the camera steady. Not perfect, but very helpful when using slow
speeds or wanting a higher f-stop. Leaning against a wall helps too, just
give the art enough space so the guards dont worry.
3) Not using a flash is a wise choice for many reasons, the first that's
it's usually against museum policy. Second that if exhibits are behind
glass all you'll get is a shot of your own reflection. When you want a
shot of something behind glass a) shoot at an angle so reflections don't
show, b) bring an old lense cloth and clean the glass, c) if you want a
close up, put a rubber lense hood on and snuggle it up to the glass,
unless the display is disgustingly dirty the glass won't exist in the
photo.
4) As regards film, 400 and above are best. Lighting is usually poorer
than your eyes will realize. Fuji NPZ800 and Konica Centuria 800 or 1600
treat me well for print film, Provia 400 or ektachrome 1600 (EPH, handy
because you can shoot it at 800, 1600, 3200 and just check the label for
proper developing ... slide film can be very grainy at high speeds
though)

Good luck!
