what other calls would I make?
I'd say you need to make a call to an instructor (or a very experienced pilot) to schedule a bit of x-country flying with him/her.
Flying in Florida is different from flying in the UK and it will not hurt to do a few flights with an instructor before you go off on your own. And not just as a club checkout, but specifically all those things that the US does not have. OHJ, landing on grass, MATZ penetration, flight levels, talking to AFIS or A/G, you name it.
Been there, done that.
