ffmpeg does not specify top, bottom, left, right values to crop it crops by defining a rectangle and it's placement.

So if your input is 1920x1080 and you want to crop 132 from the top and 140 from the bottom, your would.
Use a rectangle with the full width (1920) and a limited height (1080 -132 -140) and place it at x/y-coordinate 0/132 (0/0 is the upper left corner).
so the crop command would be:

crop=w=1920:h=808:x=0:y=132

since you mentioned that you want to crop on the input, your probably want to change the order of your video filter options.
1st crop
2nd resize
3rd add your text
in your example you used the opposite order,...

Assuming a 1920x1080 frame:

-vf crop=w=1920:h=808:x=0:y=132,scale=1280:-4

Notes:

808 = 1080 = 132 - 140

width -4 means the nearest mod4 height for the specified width (1280), maintaining aspect ratio. In this case I think it will be 540 rather than the exact 538.666...
