Domestic air travel with DSLR - any tips?

I am taking my D200 and several lenses on a trip to Disney World, and it just occurred to me that perhaps it might cause issues going through the security line. I plan to pack the D200 body, several lenses, SB-600 and various sundries (batteries, chargers, filters, mini-tripod) into a SlingShot and simply putting it through X-ray machine. I thought I would ask here whether there are any suggestions - will the packed camera cause problems? Will I be required to unpack every piece of gear? I never traveled with a DSLR other than by car, and would like to know what to expect. Any info or tips would be greatly appreciated.
