Nope, UV NEVER punches through to the surface -- but some limited near-IR spectral bands do, and Galileo's near-IR maps of Venus in those wavelengths during its flyby provided a temperature map that matched up beautifully with radar maps of Venus' surface topography. Venus Express' far more detailed and sensitive surface temperature maps should be able to reveal any small regions of current surface volcanism. The real question is whether they will be able to pierce the cloud interference enough to also provide at least a little data on surface composition near the north pole (or at least a distinction between granitic and basaltic rocks).
