Note that sometimes the more recent firmware updates are only available via the internet connection, at least for a while. That's the case with 1032 currently I believe.
FWIW, I'm on 1032 (PN63C8000) and that doesn't seem to have caused any problems. I'm not positive if it was this update but the MJC (Motion Judder Canceling) now seems to be flawless on my set -- silky smooth "soap opera" effect with no artifacts that I can see whatsoever (I'm still trying to figure out whether I like the effect but I like playing with options and it's really kind of amazing to see the difference with films at their "natural" cadence of 24Hz vs the soap opera effect).
Also, to go wireless you'll need to pick up the Samsung dongle. How far away is your router from the tv -- you could also pick up a 50 foot network cable on amazon or something and use that...
