Hi Deathshead,
If you just want the flip-flop to display a 'one'
or nothing, then yes, you can just drive the two
segments from the flip-flop.
If the seven segment has other things to do also
then use a couple of diodes from the flip-flop
to the two segments, to prevent any back-feed.
If you want to display both a zero or a one,
then you would need to use a few diodes to feed
the appropriate segments, and use both sides of
the flip-flop, one side for zero, other for one.
