Like what?  A separate /usr file system?

Your swap size will depend greatly on your applications.  You seem to
know what you need there, so I won't comment.

OK, it looks as if you don't want a separate /usr file system after
all.  For a disk of this size, this is a very good idea.  Yes, you can
put some kind of FreeBSD file system on 40 MB, if that's what your
question is.  Obviously you're not going to have bags of space over.
You might consider using tunefs(8) to lower minfree from the default
8% to, say, 2%.  See the man page for further confusing details and a
famous quotation.
