Asking for advice on PHPStorm on the Mac with os X Lion

Hello All,

First here is an outline of my circumstances:
I'm proficient at: Windows OS, HTML, CSS, C#, OOP, SQLServer, MySQL and Dreamweaver (actually the whole Adobe CS suite). Been using some of these for 20 years.
I'm a baby at Mac OS, PHP, Drupal & Wordpress (both in php), JavaScript, Java. This is where I'm focusing my energy now and forward.
I've used Resharper extensively with Visual Studio 05, 08, and 10. I love it so decided to evaluate PHPStorm. I'm in wk #2 of that.

I'm struggling and unable to find resources to help shorten the learning curve. I did get xDebug working, upgrade to OS X.7 and PHPStorm 4.0. But, I'm spending most of my development time in Dreamweaver, switching to PHPStorm only when Dreamweaver's debuggery isn't robust enough. I'd rather use one IDE and drop dreamweaver eventually.

My questions are:
1. I would like to code a website in html with embedded php and test it in PHPStorm. I can't get that setup to work. It works fine with an html extension on the file, but not with a php extension. So, I solve this by doing a lot in code view in Dreamweaver with a php extension, and jumping back to PHPStorm from time to time to step through lines of code when Dreamweaver isn't up to the debugging task.

     Is there a tutorial or recommendation on a better way to do this? I want to keep my php and html in the same file until I get it debugged a lot of the time.

2. Is there a good link for a tutorial on the preferences section of PHPStorm? There is a ton of settings in there and I'm ot sure that I care about half of them, but maybe a lot of my answers lie in there if I only understood what I was looking at.

3. Any good advice on best practices to be able to design and code and entire website in PHPStorm, so I can abandon Dreamweaver alltogether. I don't think PHPStorm is this robust, but I would love to be wrong about that. If it takes a plug-in or two products to make this happen I'm open to that. I'm a lone developer working out of my house, so no large budgets here these days.

Thanks to everyone!
