comment Direct Geodesic with Point 2 Azimuth
The questioner's problem is to find not only the latitude extent of the bounding box (relatively simple, as you note), but also the longitude extent (a more interesting problem); see below for my answer.

comment Moving dead ahead: rhumb line, great circle or none
Recommended reading for these elementary properties of geodesics: D. Hilbert & S. Cohn-Stossen, Geometry and the Imagination (Chelsea, NY, 1952), pp. 220-224.

comment More accurate way to calculate area of rasters
If your system supplies an atanh function, then you can slightly more accurate results (less round-off) replacing log(zp/zm) by 2*atanh(e*sin(f)).
