EDIT Sept. 1, 2014: I have modified the code so that it would work with any field of any type where the typical blank values for each respective type are replaced. Testing for Null values is done first and separate from other tests, since a Null will cause any of the other conditional statements to throw an error. I left out a test for a blank currency ...

You can do with arcgis project(Data Management) tool . It will convert from one coordinate system to any other. Go to arc tools and search for Project tool in Data management and give in put your vector file and give output coordinate system whatever you want based on your your requirements.

I noticed I could define the extent in the properties of the layer, export to layer file and then to .tif in ArcMap, so figured there would be a layer python command to make this in memory. Use "gp.MakeRasterLayer_managment" to make a temporary raster layer with the extent set to be the desired file extent. export the layer with gp.CopyRaster_management to ...

The single tool most suitable to your goal is Identity, which will cut up your A layer by your B layer and not leave any polygons based on the B layer that don't overlap A. However it requires an ArcInfo license. The next suggestion would be Union, which will return all polygons cut up by overlap. This will return not only the areas of common overlap ...

This can be done with the identity tool in one step, but identity needs an ArcInfo licence. Without this licence, you can use the union tool to create a new feature class. Then you delete the polygons where the old FID field corresponding with the polygon to split is equal to -1 (those are the polygons that only belong to the polygon that you use to split)

Can you do 2 operations, one a clip, the other an intersect and then append the 2 result sets together?

Using the Cut Polygons tool within an Edit Session allows you to split polygons by drawing a line, intersections in your case.
