Answer:
1) For the sphere you can use the SLC (Spherical Law of Cosines). The HF (Haversine Formula) will work for this as well. You can use both of these on the ellipsoid and errors are typically very low (< 0.3%).
If you desire an oblate spheroid then yes use VF (Vincenty's Formula).
For flat I am not sure it matters, do you mean a plane? If so then just use planar distance.
The Geoid varies greatly so in some locations SLC or HF will be best but all other things being equal VF will be best. Basically though, no best exists.
2) Weathering is important because it: Produces unconsolidated material (parent material) from which soil is formed. Results in the formation of secondary minerals, the most important group being the clay minerals. smaller rocks are weathered to the minerals that make up the rocks.
