What would you consider best practice workflow tools for web application (PHP) development? [closed]

Question

I'm really hoping somebody with more experience can edit the question as per my examples of answers:

• using version control
• test driven development
• debugging code (xdebug for php)
• use of UML diagrams
• use of OOP for maintainable, reusable code
• use of frameworks (like Zend Framework for php) for rapid application development

Anything else or an elaboration of what I mentioned above?

Basically, I'm in the middle of forming a team of developers (I'm a developer myself) and I'd like some advice on how professional programmers/designers etc should work together and what standards/paradigms they should use.

Also, if anybody has any books or links on the subject I'd welcome that!

I did find this which I guess satisfies what I'm looking for, or at least part thereof:
