Nothing to it, but you do know you have to remove the rear wheel to get the oil pan off? Also the transmission needs to be drained too.
When putting it back together, use 4 very small plastic wire ties to hold the gasket it place, one at each corner, attach the ties "loose" so the gasket floats. Then when the pan is in place start a few of the bolts in holes where there is no wire tie, then cut and remove the ties. Keeps you from buggering up the gasket.
