Good luck on your job interview, man.
As for mailing it early, I think it's better to wait. I understand it seems it a bit pointless, but I think it's a very good policy that we stick to the two submission dates. Imagine if we had ten more members on Reading Excuses (total of 30) and they began submitting at weird times. It would get chaotic really fast.
I'd prefer to try out this structure for the first month. If it's horrible, we'll do some staggering thing, but right now, it would be a bit easier if the December submissions actually occurred in December.
I'm also intending to do another FAQ for the process of submitting and all of the formatting things that go along with it (like the format for making the topic title you'd create and such) just so we are all on the same page with that. I'd like to wait a little nearer to Thanksgiving before I make that quick FAQ. And yes, I think it's already on the Rules of Reading Excuses topic, but it would be a lot better if the FAQ for submitting was easy to find, so it needs to be a separate topic for the sake of clarity.
And for purely selfish reasons, if you waited to submit on December 1st, that would prevent me from getting distracted reading your stuff, which is probably a heck of a lot more interesting than my schoolwork...
