[sdiy] just got one of these...what can/should I do with it?

Hey guys, eternal noob here:

I just got a Global Specialties PB-503 Proto Board off a guy for free.
He thought the function generator in it would be a wacky oscillator or
something and could never get any sound out of it (hee hee). I
shouldn't laugh, though, because I barely understand what I have on my
hands. Here's a link:

I've been doing everything so far with a breadboard and 9v battery,
and sometimes a Radio Shack Learning Lab (runs off of AA's)...can I
basically replace that with this? I'm kind of freaked out by the fact
that it plugs into the wall, but it seems to only actually spit out DC
from the three little terminals at the top. How do I use this thing -
can I just use the same jumper wires I've been using with a regular
breadboard? Am I going to get shocked if I'm grabbing resistors and
exposed leads and stuff? I'm intimidated by this thing...
