Newbie here from Mobile AL with questions on my new getaway.

As stated I am new to the sailboat scene and have just bought a 2007 Hobie Getaway as our (me, my wife and 3yo daughter) first sailboat. I have never been sailing but I have been on the water my entire life with a fuel burner behind me. Now that I have bought the boat I have read that there is really no where on Mobile bay ( Mobile AL)to launch unless you have a beach dollie. My question is how do you get the boat from the trailer on to the beach dollie then to the water? Also is this a good boat to begin with. I bought it from a local that has used it maybe 10 times for $2500 including the trailer. It is in excellent shape, I hope I did not pay too much being I had no idea what I was looking at. Is there any good articles or write ups online to teach me the basics of sailing? I look forward to getting on the water with it next weekend if the weather permits. Thanks in advance for your inputs and I look forward to spending more time on this forum.
