Unfortunately no way to disable either the update messages. Chances are your macbook would not be compatible (being an earlier intel generation.) Easiest way to check is go to your Java preferences & see if Java 1.6 (Java 6) is listed;
Setting up Java for Leopard (see 2nd image).
BTW when you click on the update link on the LW program, it leads you to the LW Basic download page, not Pro.
