You can look at www.seatexpert.com under Jet Airways for a seating guide on the 777 as they are leased to TK from Jet and the seats are the same.
I am not sure about th 330 but I am flying on both these aircraft on March 31 and April 1 in C so I would be happy to post my opinions after I fly if it is before your date of travel
