Professional :: Dynamically Loading News Ticker - Vertical Scroll / Loop

I have been working on a dynamic loading news ticker for a site and have been running into two separate problems:

The first, creating a movie clip, inserting the following code:
var myTextLoader:URLLoader = new URLLoader();
var myTextField_txt:TextField = new TextField();
myTextField_txt.wordWrap = true;
myTextField_txt.autoSize=TextFieldAutoSize.LEFT;
[Code] .....

And having the clip load the text from the text file listed. In this version, everything is working fine except I don't have the ability to change the font, size, and color of the text using only flash and the text document, (to my understanding).

The second, creating two .fla files, one with the embedded font I want to display named font.fla, and the other blank named fontloader.fla. Also create an .as file in the folder with the following code:
package {
import flash.display.Loader;
import flash.display.MovieClip;
import flash.events.Event;
import flash.net.URLRequest;
[Code] .....

In this second scenario, the problem is that I can't figure out a way to make the dynamic text scroll vertically and loop, (Was trying to figure out a way to save the fontloader.fla as a movie clip, then importing it into a new .fla and just using a motion tween on the clip, but so far I'm confused by it). This second scenario is also not my first choice, because loading the text straight from a text file would make the news section very easy to update for those who don't have any design experience.
