What Rinky suggests is probably what you will end up with in your 'quiver' (although the third board might be a 6ft 10 rather than a 6ft). But probably just best to start off with and 8-9ft longboard - second hand is ideal but if you are happier with new, then you dont need anything over the top ie custom made or a top of the line. Just a reasonable mid price board (the low price ones can be variable in quality, but may well be sufficient as well). Keep in mind, as Rinky has said, probably over the next few years you will start wanting a shorter board and then maybe a narrower board etc etc. You may end up just longboarding or you might end up with the longboard gathering dust - so no point spending a lot of money on it right now.
Mostly we tell beginners that 9ft and lots of volume is their friend, which is entirely correct. However, if you are a fit swimmer then you are well in advance of most beginners and the volume may not be as useful (still useful but not as necessary). If you can pound out 10 x 1.15 minute 100 metres in the pool or do a sub 20min 1500m, then you are probably fitter than 90% of surfers anyway (not that surf paddling and swimming are directly correlated but its a reasonable relationship). 90% of surfing is paddling, but if you have that covered through fitness then you can go a bit shorter
Which is a long winded way of saying that if you are swim fit (not swim fast - being great at 50m isnt relevant) then something around 8ft might be fine. However, you wont lose out picking up a 9ft board either.
