Need more info, starting with good hoof pics. See link in signature for what's needed there. Any chance of including the xrays? Also info on diet, nutrition & what work/environment he has now.
1) is it normal or the abscess to still be draining after a week And a half?
Yes, can be. Depends what exactly is going on. Sounds severe.
2) during all this, he's become off on his hind from balancing to keep weight off his hoof on the front. He's now walking very awkward. Should I be walking him or anything to loosen his hind up?
Maybe lame in hind for that reason, or maybe just the turn of one of the hinds, if his feet are so bad generally. No, if he's hurting, don't force him to exercise, unless you can make him comfortable with padding & on yielding ground, for eg.
3) since he abscessed in his toe, there's now a hole at the toe about 1 1/2 inch long and the hoof pick goes into the hole about halfway. You can see laminea. Is there anything I should be doing and can be doing to this to help it heal better or relieve pain?
Without further info not sure, but sounds like you mean it goes up from the sole, through the laminae? If so, I'd consider having the farrier resect it & treat it for seedy toe. If it goes into live tissue, it's important for treatment to be non-necrotising. Soaking in an Epsom salts solution can be good. Also depends on environment as to how I'd manage it.
4) I can't put shoes on him, not to mention I don't like shoes, but for the pedal ostietis, I have boots for when he is worked but is there anything I should be doing for when he is turned out?
Again without further info, can only say I'd personally not be inclined to put shoes on him. It is quite likely peripheral loading with conventional rims, combined with lifestyle & extreme exercise as a racehorse, to such an immature body/hooves are what caused his problems. Yes, I'd use boots &/or pads whenever necessary, to provide protection & support. However if he's on pasture/yielding footing, not rocky, he should be fine in the paddock.
With proper management & loading of P3 & lots of comfortable exercise, bone density should start to improve. A horse's heels don't *begin* to grow strong until they're around 4yo, so he'll need protection on some surfaces for a while yet, even once they're healthy.
