Depending on the database Entity Framework, or NHibernate are likely your best options (examples in links).
SubSonic has excellent support for sprocs. It will wrap each one in a helper method and you can retrieve strongly-typed collections or entities from the results if you want. I show a way to do that in this blog post. As long as your sproc returns the same schema as SELECT * FROM TableName would, it will work with your SubSonic entities.
As far as generating classes based on your db, SubSonic generates partial classes so you can extend them as needed. You could also do mappings from the SubSonic generated classes to your actual model.
