Magician, As far as I can see in recent history no one going by your nickname has posted a question on this topic. Anyways, there is a vector analysis package in Mathematica (found in a 5 sec search) that knows about 14 different coordinate systems and can do the tricks you ask for. If your coordinate system is included you're lucky. If your system is not, you might consider extending the package. That doesn't seem to be too difficult as it is plain Mathematica code and you've 14 examples in it that show you how to set up a new coordinate system.
