i have a 98 2WD tacoma. im very confused as to what the rear differential locks do, when to use them, and if i would be able to take it off road with these locks on. is it anything like four wheel drive?

From what I understand it just locks both rear wheels and yes, you can use it off-road. I assume you have a pre-runner and not a 5 lug mini? If you have the latter then there was no option for a rear locker, but if you have a pre-runner with the TRD option then you have the rear locker installed.
If you have a 5lug there is plenty of aftermarket options for a locker.. 
When engaged, the locking differential makes both rear wheels rotate the same (i.e., they're in 'lock step').
This is good for low-speed traction, and is about as good as you can do for messy off-road conditions with only 2 drive wheels.
A locker shouldn't be engaged on the street, though ... Having both wheels in lock-step is awful for cornering.
