First of all welcome. Alot of great info here. Alot of us transitioned from the sweetwater into salt on a yak. There is a simply amazing kayak tournament the first weekend of May. It is the kayak fishing stuff tournament in Jamaica Bay Long Island. Not only is a killer fishing spot, the get together lasts up to 3 days an there are hundreds of yakers there. It is REALLY low-key and people of all levels and experiences will find plenty to do.

You can thank me later. There may be other message boards out there for fishing, fishing salt and fishing kayaks. But none beat this one and KFS for friendly sharing of ideas and no attitudes. There like here you find plenty of people willing to show you the ropes. And/or just hang out and fish with.
I just got a Revo and am going to tear up the sods this year, you are welcome to come along any time.
Good luck and hopefully you can come up to Jbay with the rest of us.
