I don't know much about the actually trimming/shoeing, but I agree with everyone else that a TOPICAL treatment (like Iodine or "rain making") will not do squat for hooves. You got to get him on a supplement. And it's going to take a little time because the hoof is going to have to grow new and better material.
I started Red on Platinum Performance CJ and I am loving it! Very expensive, but everyone I've talked to swears by it, including my equine specialist vet. Now, Red has pretty good feet, but I still believe a supplement can always help.
I mean, I take a multivitamin, and calcium, and fish oil every single day. Why shouldn't my horses be on something extra?
So I would definately be putting JJ on some sort of hoof supplement or overall body supplement to help get those hooves healthy.
I know finding a good farrier can be tricky. I'm very, very lucky that I've got TWO excellent farriers to choose from. I would not trust my horse's feet to anyone else.

It is not enough to know how to ride; one must know how to fall.
