Gil,
Looks like your driver's foot rest aka dead pedal was already weak for you to have broken it. I am 6'3" and 300 lbs and mine is still intact, even though I have a funny feeling that one of these days I'll break it! Any luck finding one since your last posting? If you really need one right away, you can get a temporary one like this one
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33700&item=7966037676&rd=1 which isn't like the one from your car but will fit there for now and will serve the purpose as you keep looking. Of course you can just wait till you find one that looks like what came with your car from the factory. I'm sure that if you just keep your eyes on eBay you can find one eventually. Oh, an alternative means of getting one would be to post your request in the parts forum and see if there's a forum member that has what you need and will sell it to you for a fair price.
I can't explain that excessive oil consumption that occurred before you put in the new, fresh oil. The only thing I can think of it that perhaps the oil was so old that it had lost its abilities as a lubricant and its abilities to resist getting boiled away and was getting burnt up in the cylinder walls and eventually its volume reduced forcing the oil light to come on.
Seems like the fuel consumption wasn't that bad. So did you calculate the average MPG over the trip? If so, what was it?
