Toasted vs. Raw: Does weight change?

Slightly. Toasting removes moisture (making them lighter by ~3-5%), but boosts flavor immensely. Ideally, weigh them raw as listed in most recipes, then toast.

Should I chop before or after measuring?

This is the 'million dollar question' of volume recipes. '1 cup chopped walnuts' usually means chop THEN measure. '1 cup walnuts, chopped' means measure THEN chop. Using a scale (grams) eliminates this linguistic confusion entirely.

Walnuts (Halves)

Walnuts are the classic example of volumetric inaccuracy. Due to their irregular shape, walnut halves create massive air gaps in a measuring cup. A cup of whole halves can weigh 30% less than a cup of chopped nuts. Weighing is the only way to ensure your banana bread is rich and nutty, rather than dry or sparse.
