/dev is already a tmpfs by default - so nothing to do.

Using a tmpfs for /tmp makes sense if you have enough RAM (I just
love tmpfs for fast development stuff :)).

In /var usually /var/log is interesting, the rest depends on your
usage pattern. ;)

Check out what laptop-mode-tools do, e.g. increasing the limit
between syncs/flushes to your device is useful. Though do not
underestimate nowadays usb sticks, the better ones have amazing live
times. :)
