useful server-side tools for online marketing?

Hi,

I'm starting out and I'm building my server with:

- Open Web Analytics (replace google analytics)
- Prosper202 (for tracking)
- A content locker
- cpanel

Anything else I could use to be more independant and get things right the first time?

Not really for SEO but for tools to deal with campaigns etc?

What do you use?

Cheers!

It might be a good idea to add a cloaking solution...

anyone?
