Your keyring would be stored in your personal home dir, if you have
installed XP on a NTFS partition(i.e.: permissions are enabled) ad you
trust that machine there aren't security risks; to decrease a bit your
paranoia level ;-) you could enable windows file encryption(EFS) on you
keyring files/directory.

Only if that machine doesn't have an internet connection. There are
OpenPGP plugins for almost every MUA.

No, since the security issue is not related to the underlying
cryptographic algorithms(e.g.: some time ago ElGamal signatures were
discovered to be weak, so in newer version of GnuPG the generation of
such keys is disabled).

The machine you are using to do crypto stuff must be trusted in any case.
