For a completely specified set of postulates appropriate for modern quantum mechanics (fully compatible but in detail differing from post #128) see my Postulates for the formal core of quantum mechanics from my theoretical physics FAQ. If you want to discuss these, please do so in a separate thread.)
I'll answer this in this thread, later today.The postulates 1-6 in your FAQ are indeed standard QT, and I subscribe to them. I've only one question: Why is it sufficient to define the stat. op. as hermitean? I always thought it must be (essentially) self-adjoint.
I also don't think that you have to change anything concerning relativistic QFT. Of course, observables must be defined by (gauge-independent) observables in terms of the quantum fields, and indeed, a particle interpretation is valid only in a very specific limited sense of asymptotic free Fock states.
