Hi Eggy72,
If I understand correctly, you want to customize the toolbars in Acrobat 9 to include the Insert Pages and Delete Pages options?
If so, please see Show and Hide Toolbar Elements in chapter 2 of the Acrobat 9 Help: http://help.adobe.com/archive/en_US/acrobat/9/professional/acrobat_pro_9.0_help.pdf
I hope that answers your question!
Best,
Sara
