Re #2... A filter like that might be doable in the lab, but I dunno if it'd work on a large scale like a lagrange parasol.
On the other hand, it might - might - be possible to create plantlife that uses infrared for photosynthesis. In that case even a shaded Venus would have enough heat energy to power an ecosystem for a good long time. That'd take some seriously 'waved-up biochemistry to pull off, though. Hm...---
