There *is* a way. Something with -o remount ro or something, but I've sat
down with man mount and played, and never quite hit on the magic words to
actually get it to happen. The syntax is pretty obtuse, and the
documentation not exactly enlightening. I've never been determined enough to
plug away at the problem hard enough to solve it.

I have no idea how often is recommended. I suggest you tweak the options to
have the partitions fscked every mount, or every other mount or something,
since you reboot so infrequently. man tune2fs for details. It has lots of
suggested best practices right in the man page.
Another thing you can do is shut down by hand, with the -F option, to force
fsck. Something like
$ shutdown now -F
which sets a flag that causes a manual fsck on the next boot.
