If you want a speed increase, then an SSD is worthwhile. You can even keep using the mechanical drives along with the SSD.
The conventional wisdom is: OS X and all apps on the small SSD. Data/personal files on the larger mechanical drives.
SSD will make booting quicker and apps launch faster. How big of an SSD depends on what you do. I just use a small one (120GB), but you might need extra space on it for some of the files you work with most often. I don't use FCX, so I cannot give advice the best SSD/HDD setup for that.

People use SSD for system, they use them on PCIe cards like Sonnet Tempo for scratch snd editing.
You have a number of chices to go with in that regard and can leave your mechanica drives where they are too.

There are some things to consider, I suppose. The SATA connectors on the 2009-2012 Mac Pros are the slower SATA II (3Gb/s). You can achieve faster speeds by using one of the SSD products that connect via PCIe slots (as mentioned by the Hatter above).
SATA II is enough for me, but you may have a greater need for speed. For PCIe SSDs, there is the Sonnet SSD and an OWC version, as well.
bEst of luck.

users and tests seem to show sata II is fine for system, only when used for scratch, L4/5 or CS5/6 does it matter and free up and use the 600-900MB/sec and cost of a PCIE card.
