From what I understand, the USRP2 scales between -1.0 and 1.0. I am
trying to boost my transmit power well over the power of the DC offset.

That is an awesome amount of LO suppression in an SSB mixer based system
(I mean the power 1/33-th of the LO). A more interesting number
given this level of LO suppression would be the introduction of a tone
(say) above the LO at LO+F and to see what the power is at LO-F (the image).

The WBX can put out about 20dBm at 520 MHz. -55dBm would be 75dB below
the desired signal, which is quite a good amount of LO suppression. If
you need more, you'll need to actively calibrate the DC offset to null
it out.

The power of the tone comes in to the spectrum analyzer at -55.6dBm

You are seeing uncompensated DC offset. What is the actual power of the
tone?
