Your s_client command does not include parameters for the client certificate that should be sent. You need to use the 

-cert certname
parameter and specifiy the client certificate. You don't need to specify the CA file as its the server verifying the certificate.

Where IE is concerned you DO NOT need to install the private key. Also, again, you do not need to install any CA or CA bundle files unless these are required to verify the SERVER certificate.

Which version of IE please? Where are you installing the certificate, are you using the Personal tab?
