Alpha effect on dynamically loaded text

Greetings,

I am working with Flash MX 2004, Coldfusion and mysql. I am dynamically loading data from coldfusion into textareas in flash. Now, I want to load new data in same textarea. I need a fading/blurring effect to mingle between these two data packets.

I am new to AS and hence would appreciate if i get a step by step description of the same.

Also, I need to sound a beep after 6 seconds of loading of the flash/swf file. please help me with this too.

Thank You,
