There's a huge difference between ABA standards that schools are obligated to follow to keep their accreditation and NALP guidelines. NALP is a completely voluntary organization to join and does not represent all legal employers.
The Nov/Dec. 1 guidelines are "General Principles" that NALP encourages schools to adopt, but I don't believe they're binding to any parties (inferring from the language "should") in order to keep their NALP membership. http://www.nalp.org/content/index.php?pid=16#part2
(scroll to bottom) Also, if you send your resume in early, it doesn't seem like there are any serious repercussions. See http://www.nalp.org/content/index.php?pid=24#handle
So...if your school didn't adopt that particular NALP standard, and you're interested in non-NALP employers (like a small firm or public interest org), by all means contact them or send your resume in sooner if you think it'll help you.
