No, if you are doing diploma in mechanical engineering you cannot apply for IIT or NIT because it has stopped taking any lateral entry admission and if you have done your 12th then you can surely apply for the JEE mains advanced.

To get an AIR of 25k you have to get marks between 160-180 and it is also based on reservation.

There are a number of books which you can follow for the GATE, just read thoroughly each chapter whichever book you follow. I am suggesting you some books:-
for production: - Production operations by Allen Robert (vol-1 & vol-2),
for Drilling - Well engineering and construction by H. Rabia,
