Answer 1

What kind of server? That's really vague. I assume you mean web applications, as the cool thing nowadays is to take these "web 2.0" dynamic apps and mix them up.

You'll want a web server. Apache httpd
Maybe a Java application server. Apache Geronimo
AJAX library. Google web toolkit, MochiKit, various others.
Some kind of server scripting language. Take your pick, Python, Ruby, Perl, PHP, C
Lots of web APIs to the services you will be using, from Google, Yahoo, Amazon, Flickr, etc.
