Hi Raja,
The literature is rather rich to answer those questions although some are very academic.
I quite like the data converters book by Franco Maloberti. It does answer all your questions. Besides, things are explained in a very practical way. I really recommand this book although didn't have a real chance to put in practice all what I learnt.
From more a practical point of view, companies like TI, Maxim, NSC ... are all contributing with very handy application notes in the matter. I'm a regular reader of TI's Analog Applications Journal. There is an article that is likely to interest you:
