Cross-ties are a godsend in this type of situation. Really. I don't know how quickly you could get some, but I would put that on the top of the list. They're wonderful
As for the patience thing, once you have cross-ties, definately try the leaving him there for lengthy periods (30 min) without really working with him, but more, sitting near him. Try working around the barn while he's there, so he gets that you're there - but not really. Then maybe he'll be more interested in watching you, than being freaked out.
With age, hopefully the spookyness will go away, and with just general experience. As for you're confidence, don't be afraid to get mad at him. Really, you need to be the top-dog for both your and his safety. A harsh yank on the shank, or a firm smack on the neck (this isn't abuse when done constructively) might just knock some sense into him! I've seen horses, typically OTTB skitter all over their owners, who just get more and more nervous. One quick smack on the neck, and they'll be more focused on "What the HECK was that!!!" instead of dancing around. And eventually, they'll chill.
Once you get him so that he can stand somewhat, really get to know every inch of him. It sounds weird, but touching them all over is the best way to make them super comfortable. Inside the ears, inbetween the hind legs - yes, its sounds bizarre, but its the strongest kind of bond = touch. The better you know them all over, the better the whole situation will be - at least thats what I tend to see. ;)
Best of luck! :)
