Yes, it has threads on both sides but they do not have the same diameter. For example, if the filter is 77mm, the outer part is 82mm.

This really depends on multiple variables, but I would suggest the 8-128. The 2-32 will do well, but if you're shooting at 24fps, with a 1/48 (or 1/50) shutter, then it gets bright, so the extra couple of stops to 128 can be helpful. ND8-128 will give you the ability to just crank your ISO up a bit if the ND8 is a little too much as the sun gets dimmer.
