I would leave at 4pm, or even better, take the train, assuming you don't have a ton of bags. From UES, 6 subway to 51st St. to E train to Jamaica is probably your best bet.
+1 if you aren't adverse to it public transportaetion is your best choice as it will get you to JFK within 60 minues and can leave at 4:45. You can worry about car transport and driving in SLC
