Hi, here are some references taken from *Algebraic geometry I. Schemes.* by Gortz and Wedhorn, Appendix E.2.  These are generally scattered in EGAIV as far as I remember.

1).  This is Appendix E.2(4).  They reference EGAIV, 12.1.1

2).  I don't see this in their list...  But I don't see why it shouldn't be ok.  You could try checking out EGA.

3).  Normality is Appendix E.2(6).  They reference EGAIV 12.1.6.  Smoothness is Appendix E.2(5), again see EGAIV 12.1.6.
