Not to demean your purchase Greg but I'm surprised you went with the year old 5 instead of the 5N, which is a pretty big upgrade for not that big of a cost jump. I'm loving my 5N so far!
Extra battery is a must. You get maybe 400-500 shots with the bundled one, and you never know when any battery will have a mishap. It's good insurance to have a backup.
Extra cards are must. I recommend Sandisk Extreme as mine have been run over by firetrucks and left in water overnight and still kept working, others may disagree and say they are all the same, but YMMV.
The 16mm fixed lens is a decent one but not all that sharp in the corners, especially on the upcoming NEX-7 which really stresses it. I got mine for $100 bundled in with my kit and I consider that a bargain worth taking.
The 30mm macro is slower at f3.5 but AWESOME quality.
