Welcome to YT, as for potty training, my experience with now 4 passed yorkies that I raised from 8 week old pups, they were 100% pad trained by 5 months old, at 7 months old they were 100% house broken. I have had poodles and mini Schnauzers, house breaking yorkies I found no diff. then the two other breeds.
This girl is 5 y/o, was an indoor baby. I would keep a pad down for her for just in case. Dogs prefer to potty out doors. Consistency is the key word for house breaking any dog. If fed twice a day, they must be fed every day the same time in the morning and evening, you cannot deviate from feeding time. Every dog is diff. as to after eating how soon they will have to go out, my dog needs to go out 10 minutes after he eats, some dogs 20 minutes some 30 minutes, so this will be a hit and miss until you figure how long it takes after she eats. If it was me, 15 minutes after eating I would take her out, if you leash walk her, walk her 15 minutes. If you have a yard that you choose to let her use, I would take her to the yard supervised by you 15 minutes after she eats, keep her out side for 15 minutes, they like to sniff everything. This is NOT play time for her so no playing, tell her what you want her to do, pee-pee or poo-poo what ever word you choose is what you tell her to do. After 15 minutes and she has not pottied bring her back in the house, wait 15 minutes and start all over again. You need to know your dogs clock, once you do be consistent with out time to potty. Feed same time every feeding, walk same times every day after eating, If you can walk in the afternoon, again it MUST be the same time every day. Schedule and Consistency is a MUST. You CAN house break an older dog. Dogs are creatures of habit, they get used to doing things like walks or outside time they have built in alarm clocks lol. When ever she does her business make sure you have treats on you when you take her out , give her a treat and praise like crazy, make a big happy fuss.
Sorry, I have no help for barking, I have never had a dog that was an excessive barker. I do hope you adopt her, if you LOVE her now that love will only grow deeper for her when she is yours. Good luck in your decision, and please keep us up-dated.
