The best way to answer questions like this yourself is to record a macro doing the task interactively and then examine it to see what objects and properties it uses. In addition, the Excel VBA Help file will give you lots of information.

For your first question, check out the Font object.

To insert a column, look at the Insert method.

For the last question, check out the PageSetup object, in particular, the xxxHeader and xxxFooter properties.
