2. How to install the icons?

That isn't hard. Just startup the program `IconUpdate' found in the `Extras' drawer. Now drop the icon you want on the window and you will see the icon image resting there. This is the SOURCE icon. The following you should do is drop the DESTINATION icon on the window. This is the icon which will be transformed to the new Guide icon. After you do this, the window will be cleared and you will see that the old icon is magically transformed into the new Guide icon. ALL the tooltypes and the position of your icon will NOT be changed! ONLY the image of the icon will be replaced. Well you have an empty `IconUpdate' window now, so, if you wish, you could start all over again with another icon. Have fun!
