Database Best Practices

To all the database experts out there:

As I begin to design my PostGreSQL tables, I'm looking for some
over-the-shoulder advice on the order of "best practices" recommendations.
Has anyone gathered their experience together into such a book or website?

For example, I'd like to know, in designing a name-and-address table,
  - should a title field be provided? (Mr., Dr., etc.)
  - how about a suffix (Jr., III, etc.)
  - how many address lines should I have for a home address?
  - should all the fields be type 'text'? Should Zip be 'text' or 'int4'?
  - what schema handles Zip-plus-four best (including the blasted hyphen)?
  - what is the best database schema for a universal, international
address table that includes individuals and companies?

Now that I know _how_ to create tables and columns, I want to know
_how_best_ to do so.

Thanks for your tips.
