Look at your maya docs that come with the program under particles.

put them in a separate scene if you have to, it's not an ideal situation but it would work.

Or you could apply a matte material to your objects (E.g. matte opacity "black hole") and that would give you just the fur rendered, NOt sure how that would work with volumetric lights though.

You just need to render them alone. Depending on your needs you can hide everything else or create "matte" shader so that the geometry in your scene obstructs the areas where you want to hide your effects.

EDIT: Pure, you beat me by one minute

to get a z-depth you have to render as iff's and then you can view them in fcheck by pushing z. There is allgedely a way of getting maya to render it as a separate file but I can never get it to work. You can get a plugin for photoshop that will allow you to read iffs as well.

You'll find the plugin here.

As for the lights I'm not sure, sorry it's not something I've played with.

Hmmm...a little bit late, I guess...anyway:

Over at Highend3D, you'll find some shaders to render out a separate z-depth pass. Maya's z-depth is 8-bit only, so it comes out aliased. With the mentioned shaders, you'll be able to render the depth info ito 16 bit image files.

Not correct. The Z-depth in maya is 16 bit. The reason ppl think it's 8-bit is that if you open an .iff file in photoshop (using the .iff plugin), it will crunch it to 8 bits and do some other nasty things to it too. Also the Z-depth is not supposed to be antialiased because that would cause incorrect depth info. The trick is to mask the z-depth with alpha...
