Answer 1

Depends what type of technologies you're using. However, I'd have some sort of authentication system for your users and particular content. Make sure that you use some sort of encryption on their password (MD5 for example). Don't store their passwords as plain text anywhere. Be cautious of what data you keep stored in sessions/cookies. Make sure that you regulate the type of input allowed, and don't allow people to be able to input code/queries/etc... You can easily inject code if this isn't handled properly, and someone that knows what they're doing can cause serious harm to your database.

That's just a few things off the top of my head. I'd research further into it all, and read up on it. Again, depending upon what frameworks you're using, they often touch upon this subject or have a lot of resources to help you do what you need to.

Answer 2

You don't.
