[Zope] Beginners questions

1) Is the Zope Book available in downloadable HTML form? 2) Can I (and are there reasons why I should not) get Zserver to work on Port 80. I don't want to confuse my users. 3) ZPT vs DHTML. Straight away I am confused by this, and I need to know which to focus my attention on. I get the impression that the preferred order is ZPT, DHTML Methods, DHTML Templates. I came to Zope from programming in Python, if that helps. My plan is to start with ZPT - is that correct? 4) Is here a more appropriate place to ask beginners questions? thanks, Eddie.
