Welcome to the SL neighborhood, Drew!!!  As for your questions . . . 

1) I'm not using it, and 2) maybe Conky? I don't know if Conky is in the
SL repos or not. I don't think that there are other (similar)
extensions, though. All in all, the GNOME devs didn't want all of those
widgets in the top bar (not that I agree with them, per se).
