I recommend having LUKS be "under" LVM. the layers would be: /dev/sda -> partition (/dev/sda1) -> LUKS (/dev/sda1_crypt) -> LVM physical volume -> volume group -> logical volume -> filesystem
The layers described above are how the Ubuntu installer sets up an encrypted LVM filesystem. As far as I know, TRIM is passed through LUKS and the LVM layers if it's available in the hardware.
