As long as you don't try to run a stripe set (mechanical or SSD), then you'd be fine. If you do go this route however, you'd need to get a card to run the Windows disk, as it would no longer work on the SATA controller built into the chipset (ports on the logic board).
I don't pay as much attention to OCZ's details, so if it has 8GB of non-user accessible capacity, that's a good thing (Intel does the same, and they set it to 10%). Assuming it is 28GB for a 100GB disk, then the OCZ would have sufficient reserve built-in (28%).
The general rule is 20%, as not all makes have anything set aside, and not all that do, have 20%. Even Intel doesn't do 20%. That's something that has to be kept in mind with whatever drive is chosen. Then use it accordingly. 😉
As per wear leveling, it's just the practice of keeping unused cells available to replace those that have died (or result in corrupt writes if they can't be replaced with a "healthy" cell). But if there's an insufficient amount for the intended lifespan of the drive (typically 3yrs), you'll end up with corrupt data.
