Lori, I was hoping for some photos, so I'm glad you posted them. It looks like a nice place, and it sounds like you've got solid ideas about how you can put the space to best use. I look forward to "after" photos when you've made it your home.
It's hard to be absolutely certain, but the plants in the photo look to me like peonies. If they are, then they're finished blooming, and they always look a bit ratty at that point. Some water will likely help them have a good spring next year, but they won't put on any new growth or really do much more this year. I plant other things around and between mine that will fill in after the peonies have finished, and I cut the peonies to the ground when their leaves start turning brown (which won't be long).
