Some would rebid 1 NT as East. One advantage of this is that it limits the hcp in the hand, says its balancish, and has tolerance for pards suit.
Using checkback stayman over 1 NT if in the 9+ region pard can check for a 4 card other major or 3 card support for his major.
The more normal alternative to 1 NT is 2C, not 2D.
The 2D rebid is wrong in pretty much any system. Less experienced players often seem to think they need to rebid a five-card suit to show they have five. Personally I strive to not rebid a five-card suit - I only do so as an absolute last resort.

Is a normal auction.
2D is what is commonly called 'false preference'. You prefer diamonds to clubs because partner rates to have five diamonds and four clubs and usually you would prefer to play in a 5=2 fit rather than a 4=3 fit.
