Andy,
Why don't you begin with finding out what kind of native ferns you have in your area. And then research their habitat of occurrence to see just what ones would be good for your locations.
Below is a link that lists the ferns that you might enjoy.

For full sun the Osmunda might be good but require an acidic and boggy situation-something that is easily accomplished.

Growing ferns from spores is a rather lengthy process, unlike seed plants. Check the process outlined on the link below.
If you want to plant them in the garden next spring, I would suggest checking your local box stores or you may want to place an order online. There are several nurseries that offer a wide selection of hardy ferns, such as Bigdipperfarm.com, that offers about 125 selections, most of which would be hardy for you. Fancyfronds.com, owned by Judith Jones and Foliagegardens.com owned by Sue Olsen, both recognized experts in their field.
I have purchased plants from Big Dipper Farm and Fancy Fronds and have been well satisfied with their quality and prices. I have not had experience with the nursery you mentioned, their plant prices/S&H costs have always sent me searching for alternative sources.

Thank you both for the information. I will start reading up.
