Noobie to PS3 on OFW4.82

Hi guys-
Sorry to bother with noob questions, just picked up a PS3 FAT CECHA01 that is on OFW4.82.

I want to go the the latest CFW I can. I see CFW 4.85 is out there, but also read that OFW4.82 already had a straight hack to CFW. I looked, but the flash tool links are dead for 4.82 to do it.

Is the best path then to upgrade from OFW4.82 to OFW4.85, and then to HFW4.85, then to CFW4.85? Or is there an easier way just using OFW4.82?

I've read a LOT of PSX articles, just looking for expert...
