Well for the bar, and I'm assuming you're talking about a drag bar, I attached a tutorial that Billy T. did that helped me out. I can't answer the other question, but I think it's probably somewhat more involved. I think you'll have to stick with using an alpha effect as opposed to a mask. Masking and dynamic text don't get along so well.
Is this the effect you're looking for for the text? (scroll the pictures)http://www.networkshadow.co.uk/page.htm
A member named Marcus (i think) did this site, but if I remember right, he wasn't willing to share the code.
I'd like to know how to do it too!
