<www-style@w3.org> mailing list is the place for
discussing the further development of CSS. (The CSS
working group also uses that list for most discussions.)
Everybody can

member organization, you can also join the working group.

Software
Nearly all browsers nowadays
support CSS and many other
applications do, too. To write CSS, you don't need more than a
text editor, but there are many tools available that make it even
easier.
Of course, all software has bugs, even after several updates. And
some programs are further ahead implementing the latest CSS modules than others. Various sites
describe bugs and work-arounds.

Learning CSS
For beginners, Starting
with HTML + CSS teaches how to create a style sheet. For
a quick introduction to CSS, try chapter 2 of Lie & Bos or Dave Raggett's intro to CSS. Or
see examples of styling XML and CSS tips & tricks.
Another page also has some books, mailing lists and similar fora, and links
to other directories.
The history of CSS is described in chapter 20 of the book
Cascading Style Sheets, designing
for the Web, by Håkon Wium Lie and Bert Bos (2nd ed.,
1999, Addison Wesley, ISBN 0-201-59625-3)
