...you'll then be able to use the standard normal distribution with
mean zero and unit variance.

Doesn't your suggestion fit only if the curve is standard normal?,
i.e. mean
0, SD 1?
Perhaps my use of integral is incorrect; what I want is the area
under the
curve of a normal distribution, mean 2.05, sd 1.75 for the portion >=
threshold =1, and then the portion < 1

I may be missing something here, but can't you simply use the normal
distribution with mean=proportion z >= some threshold, q=1-p and
variance p(1-p)/n? No integration involved.
As I said, I might be missing something!
