Almost everything you need to know is documented on the GnuRadio homepage[1].
The best place to ask is probably the "discuss" mailinglist [2]. There
is also a #gnuradio IRC channel on freenode which is very active.

The easiest way is probably to emulate one of the many SDR projects
out there and use their driver interface. Other than that it shouldn't
be too difficult to get the data into GR, once you get it into your PC.
Writing an signal source for GR is pretty easy. The big challenge is
getting the data into the PC with high rate and that largely depends on
your choice of hardware interface between the FPGA and the PC.
