I think it's no problem. My /etc/fstab looks that way:

	/dev/ad0s1b     none           swap    sw        0       0
	/dev/ad0s1a     /              ufs     rw        1       1
	/dev/ad0s1d     /tmp           ufs     rw        2       2
	/dev/ad0s1e     /var           ufs     rw        2       2
	/dev/ad0s1f     /usr           ufs     rw        2       2
	/dev/ad0s1g     /home          ufs     rw        2       2

I don't know how to "expect" swapping. As far as I understood, the
system decides by itself if to write data to / read data from the
swap file. I'm not sure if you can omit it.

Yes. The access time for files won't be recorded. Using the noatime
option is often advised for the use with SSD media, so is ANY advice
that helps to minimize read / write cycles in order to increase the
life time of the media.
