First of all, i've already read and a friend explained the pros and cons of CMOS and CCD but i didn't ask about sizes and useful pixels. I mean, i get lost when i see charts and drawings of the different sensors, which are the useful areas and i definitely start to cry (not literaly) when i hear full frame.
"Full frame" just means "the same size as the traditional 35mm film camera film frame", which I understand was long ago called "miniature format" (as opposed to medium format or large format).

Then you already understand! Really!

1.5× (or 1.6× for Canon entry-level cameras) is just the ratio between the sensor used in that camera and the 35mm film format, and it simply expresses how much narrower the lens behaves, as you say above. So a 50mm lens is a normal lens on full-format, but the 1.5× narrower field of view makes it a short telephoto on a 1.5×-crop dSLR.

Filmmaking is a very broad term, ranging from coming up with ideas, writing the thing, actually making it, and distributing it. You might be studying all of that, or you might be focusing on a more particular part, like cinematography, which is the photographic aspect in particular.
