Do I need to get into swimming first ?

Up to a point, but not necessarily more than that. You need to be
able to /deal/ with being in the water with reasonable confidence
and calmness, even in potentially nasty situations.

Swimming in a BA and wetsuit (or even more so in a drysuit) isn't
much like swimming like you'd learn in a swimming class. On the
one hand the extra buoyancy means you can't sink but on the other
it makes any sort of rapid progress bloody awkward! But you could
well need to tow a boat while you're in the water and if it's sea
paddling you're looking at then you'll need to maneuver around in
the water in order to get rescue techniques carried out. This
doesn't require much swimming technique, but it does require you to
be able to keep your head and do what you're told while being cold,
wet and possibly scared. If you can swim 50m in clothes you're
more likley to have this level of basic confidence.

Aside from that, any extra level of swimming ability certainly
won't /hurt/ if you spend your time around nice water areas,
especially if they have strong rip tides. Plus the arm exercise
probably won't do your paddling any harm.
