I think you'll want to plan on some brush piles as well. I look forward to hearing what some of the pros have to say, but it sounds like the inlet side is the main problem. Which I would think will be the easiest part to work on. As you said it is firmer ground. I'm not sure what your plans are but I think I would remove almost all of the old dam and just leave enough to make a peninsula on both sides. I would also plan to put in a sediment pond above it that can double as a forage pond.
Try to post some pictures if you can. Everyone likes pictures.
