I thought metal curries were for cleaning the other brushes, not horses?
1) hoof pick, rubber curry, dandy brush, body brush, comb (really works on the body to break up large mud chunks)
2) I tend to start with the face, then do the neck, then back and legs, so im not putting dirt where I've just brushed.
3) Face is quite important because of where headcollars/ bridles sit, you don't want mud there
Body is pretty important because of where the saddle and pad sits, see above. plus you want your horrse looking clean, you can't miss the body!
Legs- not so important really, I just do mine out of habit
Hooves are pretty important for your horse to be comfy, you don't want things getting stuck in there. Plus its important to check for things like thrush.
Mane and tail aren't as important, I do them out of habit. More regularly for one of my horses but that's because he's an arab and I'm trying to grow his mane to accentuate his gorgeous head (:
Mount up and leave your troubles behind on the ground.
