Good for you to want to adopt this girl! I think you're two concerns you may run into any dog not just a yorkie. And with some dogs you will need to do some extra training and give more attention

* Barking, yorkies do bark but this girl sounds like she's in a kennel setting and has some anxiety about her location. I'd imagine some of this would subside in a home setting but she would alert you to any noises etc. But the anxiety will take some time. My concern with the barking is if she's fearful which could cause biting or ability to be around other dogs, the SPCA should be evaluating her for this so should alleviate some of that concern for you.

* Potty Training, I won't sugar coat this for you. My experience with 2 yorkies from puppy to adult is that it was and has been a struggle with potty training. You'll have to crate train to acclimate her to your home and rules but given she's 5 and may experienced using pottty pads you may want to start having options. If you don't have the patience because it can take some time and consistency on your end this dog may not be for you.

I do hope this helps. Good Luck.
