Default Solid rocket motors-some questions

I've been firmly told to start rocketry with solids. I have some questions.
1)how do you do casing cooling?
2)how to make sure fuel burns at rate casing can withstand?
3)can rocket candy be made by mixing ground oxidiser with already molten sugar?
4)is using an empty gas cylinder as a casing a good idea?
5)how does rocket candy react to water and seawater?
6)how can nozzles be made?
7)what should I expect from thermal expansion problems?
