I wouldn't recommend breaking apart each button with the way this site is laid out... If you do that you'll lose the button qualities of each button.

I do agree with you that you need to label everything better to figure out where everything is.

Instead do this: On each layer that is a button lets use Layer 30 for example.

Double Click on Layer 30 - this will take you into Symbol 244 which has 4 layers. (actions and three others)

Layer 1 is your text Layer - hide the rest of the layers and double click on layer 1, then double click AGAIN. Now you can edit your text.

Repeat this for each layer that has buttons.

Hope this helps,

Scott
