I don't think so. You'd have to get Rob to clarify it that seeing as he's the only one who really knows about that sort of shit.
BBallSim - no. SoccerSim - maybe in the future, not at the start though. Seasonal Rugby will have it once they find an actual simulator, however.
Nah, the sim doesn't 'know' about the postcounts. What you need to do is have the postcounts influence the attributes that are entered into the sim.
