keychain is indeed a great tool. It starts ssh-agent on its own if it
isn't running. You don't have to start ssh-agent yourself if you're
using keychain.
Read man keychain to learn how to install it.
For example, adding the following lines to your .bashrc will load 2 ssh
keys and a gpg key. If the agents are already running and the keys
loaded, it'll show a few messages. If they aren't, it'll start the
agents and/or load the keys and then ask your for the passwords.
keychain id_rsa id_dsa 0123ABCD
[[ -f $HOME/.keychain/$HOSTNAME-sh ]] && \
source $HOME/.keychain/$HOSTNAME-sh
[[ -f $HOME/.keychain/$HOSTNAME-sh-gpg ]] && \
source $HOME/.keychain/$HOSTNAME-sh-gpg

ssh-agent doesn't load the keys. ssh-add <file> does. But again,
keychain does that transparently. You don't have to use the command.

The output from ssh-agent has to be read by your shell. That's why
ssh-agent is started with ssh-agent bash (or whatever shell you're
using) when it's not started in daemon mode. Using keychain, the agents
are running in the background and the variables are set accordingly.
