Questions about marine corps training and college?

I am joining the marine corps as i reservist. since i couldnt leave in time for the 92 day reserve program i will be doing all my training at once and starting in the spring. what exactly will happen when i finish boot camp. MOS school, MCT or what? and how long will it take? do i get to come home in between? my recruiter hasnt informed me very much. also what is the differences between starting college in the spring rather than the fall? and my recruit mentioned something about getting college credit while in training?
