Can't help you with the cart ID, but that is a nice TT! Hope you enjoy it. I have run an A/T and Ortofon/Digitrac cart on mine. Member "Beej" is very knowledgeable about this line of Pioneers and perhaps he may chime in too.
Needle looks like an S44E to me, though with pics one can never be quite sure - but if it had a greenish tint to it in reality, my guess should be correct.
S681E³S: Nope, nope and nope. These all are older style needles, whereas the exemplar in question belongs to the newer ones (should be 241/242 over on Turntableneedles...). Easiest indicator are those little round "ears", which probably are meant to provide a better grip...
