Personally I don't think it's worth it - if it were me I'd save my miles for an international J or F award on Thai, Singapore or Lufthansa, and save the co-pay for a few drinks in Sint Maarten. YMMV though, and if this is a special occasion for you and want to fly in domestic F, then by all means go for it, there are worse things you can spend your miles on.
Two checked bags, unless Star Gold or higher
And yes, a full meal, good rule of thumb is to dummy book on usairways.com Scheduled flight time is 4:05 and the dummy booking says Lunch.
Also, depending on what day you fly, it looks like PHL-SXM is either an A319 or B757. The 757 has "envoy" seats that recline 160 degrees. 319 will be a standard domestic F seat.
