i would think that your local DNR or land conservation or local nursury could answer these questions better to your specific soil and desires.

there are many threads on the site that address these questions indirectly, so maybe a search will also yield what you are looking for.

I have used Ernst Conservation Seeds and Wildlife Nurseries Inc. There are many companies you can purchase from by mail order. Native seed tends to be a little bit expensive. I used creeping red fescue on a steep slope and it worked out o.k. If you can find a place you can go to in person you can save a lot on shipping. Some turf grass and highway grass seed providers also have some native seed for sale - especially if your local towns or DOT have native seed percentage requirements for roadsides.

I have ordered from Spence Nursery http://www.spencenursery.com/ Their prices and service are top-notch and they are user-friendly. I have ordered SOG and LBS. I recommend them.
