How do I structure my SQL Database (tables, Schemas, users, stored procedures etc.) to prepare it for an n-tier architecture?

Well, best answer is - not at all. Don't et me wrong, but..... the sql structure is not really dependant on how the application is structured.

The one mistake I did in the beginning of my programming days, is not use a database class there are many out there, I have one that I have added to over the years, but this will speed up your development time. As far as database goes there are so many rules and things you learn with trial and error... the internet is a great resource. SQL is pretty easy to pick up.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
