Sforzando itself doesn't take much space; it's ultimately the accumulation of many sfz sample files (which are the sounds you hear) that can ultimately take up space. BIAB ships with only a handful of sfz files, so you should be fine leaving it there. Sfz files aren't huge libraries, however, so you should be fine using the 32-bit version with BIAB, but if you also use a 64-bit DAW, you can use the 64-bit VSTi, which gives you lots of options. And you also get the standalone version (which you've discovered), so you can also do play along with whatever MIDI input device you have.
