Since you aren't very experienced, I would recommend you get an experienced horseman to help him get over his issues. What problems does he have under saddle? We could help you more if we had specifics. As for the spooks, you can work on that on the ground. Lots of sacking out. Introduce him to lots of scary things(umbrellas, plastic bags, bells, feed bags, etc) and don't take the object away until he is comfortable with it. There are tons of great sites, and threads on here, about sacking out.
