Navy Orders Question?

I've im in the Navy and I just finished A school and I got orders to FLT DEMO RON UIC 30929 in Pensacola, FL. I don't really know to much about it. If I'm stationed on a ship but I'm in my home port do I live on the ship or will I live in the barracks while my ship is not on deployment? Also I live in California and I'm currently in Meridian, MS. I'm going home on 14 days leave will I have to pay for my own plane ticket back to Florida? If you know anything please let me know.
