The novel can, and should, be read cold. Don't approach it like an academic or a scientist, it will ruin all the fun. Let the prose drift over you, experience it, don't get so caught up on pointing out all the references or what you don't understand. Save all that for the 3rd or 4th reading, if you like it enough to want to revisit it (as I do). It's challenging, but far from impenetrable, and it doesn't absolutely need anything to be read or enjoyed other than the text itself.
