  Zw~049.057 is a moderate mass, dusty, early-type galaxy that hosts a powerful
compact obscured nucleus (CON, L$_{FIR,CON} \geq$10$^{11}$~L$_{\odot}$). The
resolution of HST enabled measurements of the stellar light distribution and
characterization of dust features. Zw~049.057 is inclined with a prominent
three zone disk; the R$\approx$ 1kpc star forming inner dusty disk contains
molecular gas, a main disk with less dust and an older stellar population, and
a newly detected outer stellar region at R$>$6~kpc with circular isophotes.
Previously unknown polar dust lanes are signatures of a past minor merger that
could have warped the outer disk to near face-on. Dust transmission
measurements provide lower limit gas mass estimates for dust features. An
extended region with moderate optical depth and M$\geq$
2$\times$10$^8$~M$_{\odot}$ obscures the central 2~kpc. Optical spectra show
strong interstellar Na~D absorption with a constant velocity across the main
disk, likely arising in this extraplanar medium. Opacity measurements of the
two linear dust features, pillars, give a total mass of
$\geq$10$^6$~M$_{\odot}$, flow rates of $\geq$2~M$_{\odot}$~yr$^{-1}$, and few
Myr flow times. Dust pillars are associated with the CON and are visible signs
of its role in driving large-scale feedback. Our assessments of feedback
processes suggest gas recycling sustains the CON. However, radiation pressure
driven mass loss and efficient star formation must be avoided for the AGN to
retain sufficient gas over its lifespan to produce substantial mass growth of
the central black hole.
