Isaac,

Take a look at the version of usrp/host/apps/test_usrp_standard_tx.cc
that's currently in the trunk.  As of [10640] yesterday, it tunes
the daughterboard, sets the gain, etc.  It's not a beautiful piece of
code (it was written to help track down a bug), but it does show the
basics of transmitting using usrp_standard_tx directly.

One level up from that, there's an all C++ example that is pretty much
functionally equivalent to usrp_siggen.py  It uses the GR usrp_sink_c
block from C++.  See gr-usrp/apps/usrp_siggen.cc.

Neither of these examples are "ready for prime time".  Neither handles
^C properly (they leave the transmitter running).  YMMV.  But they
will give you some ideas.
