TRIM and changing mount options

I've some what blindly followed a how to on installing FreeBSD 9.1 on a ZFS mirror.
My typing is horrid so I simply ssh'd to a live CD env and pasted line by line as per the how to found here;
All is well, no issues with replacing disks, testing failures etc...
But seeing that my system drives are SSDs, I thought to perhaps add noatime, etc... to avoid slow downs common in excessive SSD usage.
However my fstab is only mounting swap partitions and I have no idea how my file system is being mounted :)
Also, I would like to use tunefs in finding if I have TRIM enabled as I did load it via boot.conf
I kinda feel like I'm willy nilly adding load lines w/o seeing if I actually have the TRIM patch installed :)
At any rate, could some one;
a) Explain how I am loading my file system as I'm used to fstab?
b) How to run tunefs on my zroot
c) How to determine if I actually have the needed TRIM support in my kernel
I'm running 9.1 with the latest updates via freebsd-update (fetch/install).
Thanks in advance,
