Hi Michelle... yes most will remember you and Gretchen!
Great improvments... remember baby steps and one thing at a time as to not overwhelm you or her. Eating everything, yes, some dogs are just that wasy -- right @JAKEISGREAT. My girl has a very high prey drive and when outdoors, if it moves it is pounced on and eaten, however, through constant training, indoors she does not touch anything she should not (the collar you are using was our source too).
UTI.. does she sit very close to the grass when she pees? If yes, you should wipe her 'girl' each time she goes. I recently posted about having this issue with Banks.
