Replying potential PhD supervisor with documents I applied for PhD at a University and receive a mail from the supervisor, he asked me to mail my cv and transcript. I am thinking to reply like this:


  Dear Professor XXX,
  
  Thank you for your reply.
  
  I have attached my grade sheet and resume, with references, to this email.
  
  Thanks for your consideration.
  
  YYY


Is it sufficient and decent?
Yes, this is sufficient and decent.

Only point I'd note is that if your transcript is not in English, be sure to include a translation. You might also need an explanation of what the grades actually mean (e.g. is your grade measured on a 4.0 scale, or on a 100-point scale?).
