Got to messing with it and actually made it work by coming at it from the other direction. I unchecked remove spacing from paragraphs and am using this in my stylesheet:
Code:
p {text-align:justify; margin-top:0em; margin-bottom:0em; text-indent:1.5em;}
blockquote {text-align:justify;}
h1,h2,h3,h4,h5,h6 {text-align:center;}
.indent {text-indent:1.5em;}
.noindent {text-indent:0em;}
.center {text-align:center;}
.spaceabove {margin-top:1.25em;}
.spacebelow {margin-bottom:1.25em;}
.spaceboth {margin-bottom:1.25em; margin-top:1.25em;}
