dynamic text formatting...

I'm pretty new to ActionScripting, and am trying to change some of the formatting on some code...I've been stumbling through tutorials and putting pieces together roughly. Is there a simply way to change the font and justification of this text? code is as follows:
var nWidth:Number = mcDisplayBackground._width;
var nHeight:Number = mcDisplayBackground._height;
var nX:Number = mcDisplayBackground._x;
var nY:Number = mcDisplayBackground._y;
var nInterval:Number;
this.createTextField("tArticle", this.getNextHighestDepth(), nX, nY, nWidth, nHeight);
tArticle.multiline = true;
tArticle.wordWrap = true;
tArticle.html - true
tArticle.textColor = 0xFFFFFF;
tArticle.htmlText = "Founded in 1989, CYW, Inc. has established itself as the leader in the construction fastener industry.";

mcScrollUp.onPress = function():Void {
nInterval = setInterval(scrollArticle, 50, "up");
};
mcScrollUp.onRelease = function():Void {
clearInterval(nInterval);
};
mcScrollDown.onPress = function():Void {
nInterval = setInterval(scrollArticle, 50, "down");
};
mcScrollDown.onRelease = function():Void {
clearInterval(nInterval);
};
function scrollArticle(sScrollDirection:String):Void {
if(sScrollDirection == "up") {
tArticle.scroll--;
}
else {
tArticle.scroll++;
}
updateAfterEvent();
}

Thanks!
