Not my particular field, the far east, but one 'photo album' type book I have, which has some detailed accounts of the far-east air war, is 'Beaufighter at War', Chaz Bowyer, Ian Allan Ltd., 1976 (and re-prints) ISBN 0 7110 0704 7.
If you can't get hold of a copy, and you think it might be helpful, you can borrow my copy, on the usual proviso.
Also, I've noticed over the past year or so, that more books are emerging covering the 'forgotten war', and a quick look at some of the advert pages in 'Flypast' or 'Aeroplane' magazines, might turn up something useful covering SEAC operations. good luck with the research, and let us know how the dissertation goes!
