I was just wondering where it was - would have expected to see one on such a well used forum
And no, I'm not volunteering - I'm a relative newbie too and my commute is fairly short, so I don't have much to offer.
But there's one piece of advice I'll share for those just getting into the idea of commuting by bike:
Make sure you carry at least one spare inner tube and the tools you need to change it
I always carry two spares and a pucture repair kit too, although I can't ever see I'll need the kit until I get home and have the time to mess about 
P.S. Don't use the inner tubes with the gunk inside them that's supposed to "repair" a hole by filling it with the gunk. I tried one once and it lasted 2 miles, then exploded!!!!!!! It took 10 minutes and many many tissues to clean up the inside of the wheel before I could put a decent one back in
