A few questions...

Is there any guides on setting up a simple home installation of Zimbra? I only have one server box, a HP DL380, so can I set up bind and zimbra on the same server and use it for DNS and everything?

Secondly, is there a way to use zimbra locally like this, without giving it an SMTP server? I do not want to send any e-mails to the internet, just local testing. If I was to set it up with SMTP, can I use gmail SMTP or do I need to get one from my ISP?

I was also wondering if there are any PDF versions of the documentation pages, ie: Zimbra™ Collaboration Suite Single Server Installation - Open Source

Reason being is that I use a kindle and read a lot on the train while traveling. I'd like to learn a bit about the technology in my spare time.
