Yes, retrieving new mail works fine with or without the proxy if
evolution has already stored the imap password with remember password.

No, a password in the keyring does not change the situation.  If
evolution needs the imap password and the proxy is on, evolution hangs
whether getting the password from the keyring or through a pop-up
evolution prompt.  When the proxy if off, evolution will use the keyring
password if it exists otherwise prompt for the password.

yes

Yes, the proxy works for browsing, weather applet update, apt-get, ...
