You may need to use the psf-binary output file format and have the appropriate Save command in your netlist.  Further details depend on how you are running spectre (through artist, command line, etc.).

Unfortunately your last post doesn't make much sense, but I suspect you need to just know that you can either do:

Results->Print->Noise Contributions

or use Tools->Results Browser and navigate to the noise results. You can then go to a particular device, and look at the noise contribution of one of the noise sources in that device at the output. Note that this tells you the amount of noise contributed by that noise source at the _output_ of the circuit - so it will be affected by whatever gain there is to the output from the device.
