I can only help you with your first question :

How i did it for my druid : Right click the minimap button. Select Create new Bar. In the middle of your screen there is a new blue bar visible. Right click on it to show its menu Select Stance bar. Click on Button count and use your mouse scroll to determine how many buttons you want.
Press done when you are ready... As you can see your bar has switched its name.. instead of Bar 1- Normal. Its should now be called Bar 1 - Caster Form. Simply select Dire bear form from your spellbook. The bar will change into.. bar1 - Dire bear from and your gonna need to set the amount of buttons again. Do this for every form/stance and you should be all set.

For question number 2 : i have no clue and would like to know myself aswell :P
