Answer 1

One good place to start is the University of Michigan's excellent Animal Diversity Web

http://animaldiversity.ummz.umich.edu/site/index.html

It contains information on almost any critter or group you care to look up.

The Tree of Life Web Project, which attempts to map the phylogeny of every organism is another good source of information.
