Last question first: yes, higher velocities show less wind drift BUT the difference in drift for a 25 fps increase is so small as to be ignorable for most of us. Going to lighter bullets of similar shape is a losing battle because the reduced BC tends to give greater drift in spite of the speedier start.
A good rule of thumb: shoot for an accuracy node within about 100 fps of a published maximum load for your powder and bullet. The improvement in accuracy will trump any gains from wind drift reduction.
