I agree with Ramm, you might not see any difference with the upconverting. I used HDMI and actually had my 3575 set for 480p. I thought that looked best. Maybe you should try moving your 3575 closer to the TV to try the 12' cable you have, just to see if it will be worth it before you send off for a longer cable.
As far as tuning in HD channels on the 3575 and outputting them on your TV you should get a better PQ that tuning them direct with your SD tuner TV, but I don't think it will be anything like a true HD tuner, although since you only have a 480p TV I'm not positive what the difference will be. I know using my Panny DVDR w/digital tuner, outputting to my 24" Sony SD TV via component cables, it was only marginally better going through the DVDR tuned to a HD channel, vs the same SD channel tuned directly on the Sony. The only way you'd know for sure is to get a true standalone HD tuner and hook it up direct to your TV, and compare that to the downrezzed output of the 3575.
