If I were you I would purchase the filter first, then test it out once the waterfall/background is complete. That way it it isnt powerful enough, you can just buy a cheap pump. I think I remember you saying in another thread that this tank will only be about 20 gallons though correct? It may be very difficult to hide any sort of filter and pump without the use of a false background, or sump setup. I would spend some time researching both options.
As for the silicone, spread it evenly on the visible glass sides, then just add globs and lines of it on the glass surfaces that will be hidden (back). As long as your glass is clean the foam should have a firm grasp of it. On the visible sides, try doing a thin layer of silicone without any bubbles, then once it has dried, do a secondary thick coat to stop the light from passing through it. If you dont like the idea of using 2 tubes of silicone, then I would suggest using dark limo tint or black spray paint on the outside of the glass to hide the foam.
