Another lamp successfully changed and counter reset. Had a little problem with the latter but persisted with the standby/reset, <-, ->, enter commands until it worked.
Thanks to you all, I bought just the lamp, (now $300 on ebay), I didn't have to take my own pictures during disassembly because everyone elses were so good, and was careful to avoid mistakes.
And the lamp chatter is GONE, GONE, GONE, well, at least for now. New Edit: believe it or not, the lamp started to 'hum', perhaps sing is a better descriptor, after 18 hours. I enterd the service menu and discovered the lamp temp was over 400 degrees. I turned on the high altitude fan setting and while the fan noise is considerably louder, I haven't had the lamp noise return even after extended on times, (6 hours).
