uhd is the hardware driver for ettus products

gnuradio is the modulation tool kit + examples. Tom has ported all of
the example to uhd in the next branch.
gr-uhd is a component in gnuradio that provides usrp source and sink
blocks. This is the gateway between gnuradio and the hardware.
usrp/gr-usrp is the legacy driver that only support usrp1

You will have to change the block that is instantiated to be a uhd usrp
source or sink. There is no reason that rest of your
modulation/demodulation chain or mac layer would have to change.
