Be very careful in setting seat height, cleat to pedal axle (you are using proper foot retention ?) and gearing.
If you are comfortable w/ the SS/FW gearing match it exactly in FG, that which works, works.
Standing to stretch, and get over hills, is normal but the coasting part is out.

Leave both brakes in place should you need to slow downhill cadence to prevent hamster-in-wheel syndrome and get out away from traffic for 5-10 mile adaptation rides.
Riding FG is not for everyone, but give it a fair trial over a period of weeks.
