    In a latch iC like the one linked above. It has the Q and (Q with a line above it) outputs.
    In these outputs if "Q" is "on" sourcing current, is the other "Q" sinking current? or is it just off?

    Yes, sinking/sourcing current is one way of looking at it.

    !Q is just that, opposite of Q.

    If Q is high, !Q is low
    If Q is low, !Q is high

    Flip flops have the complimentary output, as sometimes using both is useful
