Here is the information from the Page Speed team on the checks that they are done: http://code.google.com/speed/page-speed/...intro.html

Also worth reading is the information from the YSlow team: http://developer.yahoo.com/performance/rules.html

It's difficult to have a simple explanation for how to fix them all because more often than not it depends on a LOT of different things. Compression for example (which is one of the easiest) is implemented differently for Apache, IIS, Nginx and may or may not be possible to control if you are on shared hosting.

The cache control changes you referenced above are REALLY dangerous to implement if you don't understand the implications (you can never change the content of your css/js without changing the actual file name now that you turned it on because users will use the version in their browser cache for the next year regardless of what you change on the server).

The tool is language-agnostic and does not target PHP implementations. A lot of the basic (and more important checks) are basic HTTP capabilities while some focus on the front-end resulting html. I strongly recommend reading up on the fundamentals of how browsers, HTTP and servers interact to deliver a full page. The foundational knowledge will be exceptionally helpful no matter what you are building for the web.
