Urgent: export all the backlink information from Webmaster Tools while you still have access to the WMT for that domain.
I agree with Tedster, do not worry about backlink growth being too rapid. Get as many links changed as possible, as soon as possible.
This is not a normal situation so "normal" backlink growth is not the right goal here, at least not for a while.
