So far so good, I would agree with everything that you've said so far.

No, this is the right and only way to do things. Rae's bid stands as she
bid first, and she will have to deduce that whoever has bid against her
(she need not know who) has also bid $3.00, but she got there first.
You need not ever tell Rae who is bidding against her. Just say
"Your bid has been increased to X.YY to retain control of this lot."
In fact, I would *recommend* you don't ever tell Rae who is bidding
against her.
The e-mails would read
To Rae: "Your bid has been increased to 3.00 to retain control of the lot."
To Chris: "Your bid of 3.00 was not enough to get control of this lot.
Price is now at 3.00"
Of course, both parties now have the opportunity to increase their bids.

You're welcome!
