hatrick ...welcome! Hard to understand what you mean by your question on the galley...but food is easily available in the bahamas and is of good quality and high priced. If you want to bring stuff from the states to save money...focus on paper goods, beer, soft drinks and high volume low cost stuff like cereal and potato chips...all these items are particularly expensive there.
As to a dinghy...you MUST have one in the bahamas with a reliable outboard. A rib is best with the coral but that will not be an option for you on your sized boat. Search the dinghy threads here for opinions on the different types but you WILL need one and will need to anchor quite far from shore quite often. Make sure you have an anchor system you can really trust in 30-40 knots of wind to hold your boat!
