only advice i can give you is wait untill a stable CFW is out.
i mean really wait untill rep. users report its working with most games (if not all) and there is no risk in bricking it (fail-safe methode found(recovery menu or what not))
also i would recommend you don't go online with it. as the ps3 might connect to the psn backbone and report what you've been doing.(unless u use a gateway-software that prevents this)
and as off now the only "safe" models are reported to be the slim not the old launch models.
