My experience is in Canada, so things might be a little different here. However, the midwives I saw were EXCELLENT. The care and attention you receive in your prenatal care, and during labour are excellent. They are trained in what to do if something goes wrong.
You can do your research and see for yourself that a healthy mother carrying a healthy baby, being attended by a qualified competent midwife is taking NO extra risks, and is in excellent hands. Showing that sort of thing to your husband might help. Mine is totally won over after being a little reluctant/hesitant. He's convinced that home is definitely the best way to go when you can.
My midwives cleaned up any mess left after the birth. They bring blue pads and stuff to absorb any blood or whatever during birth. I gave birth in the bath, so we pulled the plug and rinsed it out, and were good to go.
My midwives also were responsible for post-natal care up to six weeks. They checked baby's hips immediately as part of the post-birth examination (along with palate, reflexes, etc.) They checked on me daily for the first week to keep an eye on nursing, bleeding, weight gain, and any other issues I might have. I also knew that they were available to me at any time if I had a concern. I had their pager and cell numbers. I don't know what is normal for midwives in Aus though - whether post-natal care is standard or not. Regardless, you could easily make an appointment for your baby to see a pediatrician soon after birth if you were concerned.
As far as prep for homebirth goes, some clinics give you a list of supplies to get (extra towels, waterproof pad for bed, etc.) I imagine each midwife has their own way of going about things. I'd highly recommend that you talk to a private midwife in your area and see how she answers your questions. The concerns you have are pretty much the same that everyone has when they first consider a homebirth.
Have you read the articles on homebirth here on BB? They're great!

All the best with your decision!
