Retrofit new shower drain in old concrete floor drain?

Working on a shower in an old house that was left without any real shower pan, just this drain-type-thing in the floor. My plan is to put a fiberglass shower pan in to keep things simple. However, I don't have the 2" PVC tube sticking out that I've heard I should have to mate with my fiberglass shower pan.

Can I retrofit something into this or do I need to break the concrete and do a deeper rework?
Also, anyone know about that plug on the side?
I haven't snaked it yet but I'm hoping that will drain the liquid that is in there. I would imagine it shouldn't be static that high.

I would remove the concrete around the drain and replace it with PVC. It will also give you a chance to locate the trap or at least make sure there is a trap. Many older homes have can style traps which can be impossible to snake out if they clog. A modern P trap is nice and smooth so it's resistant to clogging and if it does clog a drain snake can be run through to clear it.
