That's quite easy actually...

... you might want to refrain from limiting yourself with premature conclusions ;-)
To extract a certificate, select the packet that contains the (reassembled) SSL Handshake message "Certificate". Expand the Certificates until you have list of Length and Certificate lines. Right click on the cetificate that you want to extract and choose for "Export Selected Bytes". It will save the certificate in DER format to the file you specify.
Hope this helps,
