I also read the O'Reilly book on Python - 'Programming Python'

There's Python.org for all docs, of course.

For Django - http://www.djangoproject.com - they have a cool tutorial on the front page, and http://www.djangobook.com, then move to the documentation from djangoproject.

But there is some really good PHP code out there. The problem is finding it--particularly for a non-programmer. DokuWiki is very nice. Flyspray aint even half bad. Wordpress, while extraordinarily popular, is a bit painful to look at...it's getting better, but it's not ideal to learn from (I'm not knocking Wordpress...I use it for two blogs and recommend it to everyone who asks about blogging software). The majority of Joomla is downright scary bad--I feel dumber every day that I spend working with it.

I'd suggest trying to change your "mindset" as well, building and reading supporting information at the same time. One such way is to read "SEIA" (Software Engineering for Internet Applications, Andersson, Greenspun & Grumet) which is online or in print and follow the book through ~ http://philip.greenspun.com/seia/

The book/course is easy to read and most important devoid of advocacy. The good thing is you can start now at no real cost. But it will take time and effort though.

Finally,when your app gets complex and you need to hire programmers, you will thank me for this advice
