Again thanks to all of you who have replied!
For my case, I have continued cold hosing to reduce swelling, checking for a digital pulse and/or heat, finding none, just fluid build-up I believe.
I check his temperature before beginning everything and today it was at 100.8 which is .4 above the suggested normal, but by no means a fever to even note.
Once the swelling starts to reduce, I scrub the area with right now baby shampoo with antibacterial properties that is also wax, perfume, and all free.
I dry the legs (I do this to both back legs because the other also is a white hoof, and has a matching sock, that has been exposed to the same, and most likely suffers from a pre-stage of what it's counterpart has.
Once towel dried to the touch, I begin peeling any new scabs that the hose didn't remove already (which hasn't been much of anything) When I feel that the area is clean enough, I clean and treat all hooves with a bleach and water mixture for what I think may be thrush on the underside as a just in case measure.
Its finally now that I start treating the scratches, I begin with the triple antibiotic cream, and pat on the zinc powder Calesdene or something, and send him out (while temporarily wrapped for 30 minutes or so with just some gauze and vetwrap) into the round pen to walk about, roll, etc just to get him moving.
I did hop on him bareback and did some walking and trotting which he was completely sound for, I didn't attempt canter.
The farrier is coming out tomorrow morning to do his feet, and he did (while didn't complete) attend several years of vet school, and has been a farrier for 30 plus years, so I trust his opinion, and information because it hasn't lead me astray yet.
Saturday is a big show, while I'm not against dropping, I really hope by some miracle he can say yes he can compete with what he has going on, shall I cross my fingers?
And while how I put all of this may seem dramatic, I really don't think it's bad enough to call the vet out yet, because in my experience unless doing some biopsy or something of the sort, which I would have to refuse, all he can really do is put him on an anti-inflammatory and sulfa tablets, so I don't really see the point RIGHT NOW.
Sorry for such a long post!
