Amy,
You should also give her a good multi-vitamin every day. One good brand is Pet-Tabs.
I bathe mine every week. Usually 5 - 7 days apart. I always used Pro-V on Muffin and do on Kacee. I used baby shampoo on their faces. I keep a good oatmeal shampoo to use if they develop seasonal itch.
Also, once she turns 7 her food should be changed to senior food. How are her teeth? Once you gain her trust, you will want to check her teeth for tartar buildup. I brush my doggie's teeth and also use tooth wipes to keep them clean.
