Well, it's done.
(2) 240g OWC's installed. Applications on one (47g used), documents and scratch on the other which is split 190/50. The documents also have LR catalogs, so there is 78g used out of 190.
I don't have any detailed measuring software other than the Activity Monitor, but before the switch Disk Activity maxed out at about 30mb/s; it is now over 100. It sure is faster opening applications and large files. I did a pano that used to take over 30 minutes in less than 5 minutes. Feels like a completely different computer. Office 2011 opens faster than you can move your fingers from the touchpad to the keys.
Only issue I have is occasional crashes associated with finder and external drives. Not sure what that is about, but I think it has something to do with power to the external drives because I have one eSATA drive that uses its own power supply and it has never crashed with that connected. I have had crashes with USB drives, Firewire drives, and eSATA drives powered through the firewire. I even had a crash with a simple USB jump drive. Probably be unrelated to the new SSD's. Anyway, overall a success. Thank you for your help.
