Yes.
Exactly, my offer letter is the same as yours. It doesn't mention all those informations required by CIC. But i guess CIC is aware of that, so i don't think its a problem.
For your question about the study permit application form, i put the overall tuition fee for one academic year that i saw on their link for estimated tuition fee. And they also provided the different amount of tuition fee according to each semesters for a year to me... I have printed that email and i highlighted that part so that the visa officer will see it. And for the room and board i just put 10 000CAD as they always say the yearly amount + 10 000CAD
Hope i responded to your question
