Question about Ollivander and Harry's Wand

Can someone give me the message number or name of the theory if one 
exists about Mr. Ollivander's knowledge of Voldemorte?  The lists are 
just too massive for me to search on my own.  Where is Hermione when 
you need a good research assistant?

Anyway, I was thinking about the graveyard scene at the end of GoF 
when I realized that Mr. Ollivander is one of the few wizards who 
knows that Tom Riddle became Voldemorte.  Dumbledore had once said 
(sorry, don't have my books) that very few people were aware that 
Voldemorte had been a student named Tom Riddle.  But, in PS/SS, 
Ollivander knew that the brother wand to Harry's wand had been the 
one that gave him the scar, therefore, he knew that Voldemorte was 
Tom Riddle, since the wand had been sold to Tom Riddle.

Now, was Harry's wand created before, at the same time, or after Tom 
Riddle's wand?  Did Fawkes give up both tail feathers at the same 
time?  How long had Harry's wand been sitting on the shelf in 
Ollivander's store?  Note: Tom Riddle had purchased his wand over 50 
years before Harry.  Did Ollivander ever try to sell that particular 
wand to any other wizard?  Was he waiting for the day when Harry 
would walk into his store and did he just have Harry try other wands 
first so as not to arouse suspicion?
