Microsoft office, Word 2003, Windows XP

I want to have five sections in my document.
One with lettering (i, ii, iii)
One with numbering (1, 2, 3)
One with Appendix A (A-1, A-2)
One with Appendix B (B-1, B-2)
Once with Appendix C (C-1, C-2)
My document has "page breaks" throughout.
How am I able to break my sections down where it have the lettering,
numbering and appendixes.
How am I able to by-pass my "page breaks"
