my advice? don't move.
i HATE moving.
but...my real advice would be to put all boxes in one room (someone else said that too) so you're not always surrounded by boxes; also so if you're painting, you don't have to keep moving them. i'd paint immediately, unless you can live w/ whatever's on the walls - but like you said, it'll be hard w/ a newborn. oh, and STOCK UP on rollers, brushes, stirrers, etc., b/c it really sucks when you have to stop painting to go to home depot AGAIN. we used to take nightly home depot trips - ugh.
good luck - and if you ever need to refi in nj, i know a great broker
