Did you read this:
http://www.gnu.org/software/gnuradio/doc/exploring-gnuradio.html? The
document is a bit old, but still give a very good introduction to the
basics of GNU Radio.

I read in an earlier thread that you want to do the (I)FFT processing
in the FPGA. This is not how it is intended to be used. GNU Radio is a
software radio framework, and the goal is to move as much of the
signal processing as possible onto the host computer. Moving the FFT
back to the FPGA would therefore be a step backward in the software
approach. This is just my personal opinion, so feel free to spank me
with a 10 foot monopole if your view is different :)
