If you really want to learn Quantum Gravity it is never too late to introduce yourself to General Relativity as well as Quantum Field Theory. First one is crucial for understanding Quantum Gravity because it is based on both QM and GR. So for more advanced studying I recommend this book http://www.cpt.univ-mrs.fr/~rovelli/book.pdf
It's not possible to measure the expectation values of arbitrary observables using pre-computed lattice configurations. Lattice QFT gives accurate results only for observables which are not sensitive to physics at distance scales shorter than the lattice spacing. Everything else 'slips through the cracks'. In particular, if you're precomputing ...
