Carefull with the suet, but you might be able to add it to the satin ball recipe as part of the fat source (when I was doing satin balls I used an ice cream scoop to form the balls, set them onto a cookie sheet and put them into the freezer. The next day they were solid enough to bag up without sticking to each other).
If she's having trouble getting interested with raw chicken, get your pan nice and HOT (if its cast iron you want it close to smoking) put down just the barest bit of oil, and toss the boneless breast on, flip it quick, and then pull it back off. Gives it the "cooked" flavor without cooking it through.
Definetly cut down on the sources you're feeding from. I understand what you're trying to do, but it does sound like an allergy issue and you've GOT to narrow down your focus to help with that.
Bones: if she won't do chicken raw (and DO NOT cook anything with bones in for her unless you're removing the bones before feeding), try rabbit or even pork. My Tibetan Mastiff (who's a bit smaller, weight wise, than she is) can chew up pork necks with a little work. Just don't over do the pork, the fat might be good for her, but until you're 100% on the rest of her issues it might be bad too. Also look at duck and turkey as alternatives to chicken for both meat and bones.
Watch the hotdogs, even the higher end brands have extra salt and stuff that isn't great for us much less our dogs (and might be contributing to her health issues). A little as a treat is usually ok, but not to much.
Live culture yogurt isn't usually a bad thing, and both my dogs love it.

satin balls recipe. I modified it a bit, used all oatmeal instead of other cereals, used regular geletin instead of the fancy stuff (that I couldn't get locally), but otherwise followed it for the most part. Apollo loved them.
