Thank you for your query to the Ireland Reaching Out message board and welcome to the site.
The information that you have given does not appear to pinpoint John Grady to a specific location in County Clare. However, there were Grady's in Tulla and the O'Grady clan was in East Clare, as well as West Clare.
The two baptism records that you have found are both worth looking at more closely. You might also be interested in looking at the resources that are available online through the Clare Library website. For your reference, the link is below:
I have found the baptism entry for John Grady born to Miles Grady and Mary McInerney on 26 June 1832. His residence was Scoubagh (now part of Ballyblood) and his sponsors were: Martin Ryan and Bridget Ryan. His siblings were: Anne and Mary. It appears that a John baptised in 1826 must have died as he is the 2nd child named John.
If you need further assistance, please let me know.
