Sir's/Madam's

We will re-format our test server and install
a Sun Solaris 9 or 10 OS (64-bit). I will re-install also Oracle 9.2.0.1 Database, what are the valid patches that needs to be done?
in metalink
only 9.2.0.6 and 9.2.0.7 are listed... do I not need other patches anymore? are these patches already stable?

thanks......
