1. `The solar nebula in Earth's area was composed of very few major elements`. Does `major` just mean elements that are in large quantities on earth? 
2. Does that mean that the increase in minerals was due to Earth physically redistributing elements already present at Earth's formation and thus forming new minerals, rather than new minerals (or elements) arriving from outer-bodies. 
3. Do these original minerals made in space still exist in earth, or where they re-formed into different minerals through differentiation on Earth?

1. yes, 2. yes, exactly (excluding H2O and hydrated minerals which is still debatable), 3. mostly. some minerals that are common in meteorites, particularly reduced minerals (e.g. carbides and native elements) or silica-poor minerals (e.g. hibonite) are now extremely rare on earth and occur only in very specific cases. But most minerals you find in meteorites are also common in Earth (olivine, pyroxene, etc).

Were all of Earth's minerals created before Earth's formation, during, or after?

I've heard that during the accretion of proto-planets that formed the username_2, 60 minerals were created through the reactions of atoms and molecules in the nebula.

Do these first minerals still make up username_2?  
Do we have more minerals? If so, how and when were they created?

This is a very interesting topic that in the past several years has reached the spotlight because of the work of Robert Hazen on the concept of "mineral evolution".
