would you use 75 lbs per 1000sf to lower ph from 7.5 to 7.0
and use sulfer to raise nitrogen? if so how much?
what will adding coffe ground to your soil change?

Depending on how much free calcium carbonate you have, 75 lbs/ 1000 ft2 of 90% sulfur should lower your PH from 7.5 to 7. Not really sure where you are going with the question on Nitrogen. As far as the coffie grounds, depending on how much, this should also help to lower the PH, however the grounds are primarily added as worm food.

How did the pH get this high? Did you add something to bring it up or is it just this high unammemded? What is the buffer pH?
