Asset Protection - Sub S or LLC or both

Florida
I was advised to set up LLC in Delaware for a home-based Florida real estate investment company. Now I am advised that the LLC should be owned by a Subchapter S Corp. to get the appropriate asset protection. Should I set up a Sub S in Florida or go with the LLC only?

How do you form the Delaware LLC?

I'm in CA, but am interested in a Delaware LLC. How do you set one up? Don't you have to have an address in Delaware, and if you want a bank account for the LLC, do you have to open that in Delaware too? What are the benefits of a Delaware LLC over other states? Thanks.
