That depends on the cipher in use and if it supports perfect forward
secrecy or not.

Yes, breaking the RSA/DSA key will let them read files or e-mails
(effectively a file) encrypted with that public key.  But I think that if
you are doing SSL with that public key, the key exchange cannot be
understood by a passive observer, so passively recording the packets will
not let someone later decrypt the exchange.
