Patching a Solaris 9/SPARC system

Okay - so I haven't been religiously patching my Ultra 2 (running 
Solaris 9). But short of buying a support contract from Sun (and 
therefore being able to download so much as a patch cluster!), what's 
the easiest way people suggest patching a Solaris/SPARC box these days - 
in particular, one that hasn't been patched in a while?

There's the Sun Update Connector (or similar-sounding name) but I'm not 
even sure how to go about using that if that's the way to do it (yes I 
already have a SunOnline login from way back and it still works... but 
it doesn't have a SunSolve contract associated with it).

I'd upgrade this Ultra 2 to Solaris 10... if the CPUs were supported 
(2x200MHz UltraSPARC). (On this front - can anybody confirm that Solaris 
10 will/won't work on this setup?)

Ideas? Or should I just amble along and download the odd patch or two as 
I need to? (Heavens above should I rebuild a Sun box... how I patch that 
box would be beyond me right now without a patch cluster).
