I can't believe that I can actually answer a question. I just learned the answer to your question #2 yesterday while taking lessons from a free online tutorial. Anyway, here is the answer to your second question:
"You do not always place controls on a form in the same order in which you want to set the focus. Therefore, controls that can receive the focus support a property called the TabIndex property. The first control in the focus order has a TabIndex property of 0, the second control in the focus order has a TabIndex of 1, and so on. If you place controls on the form and then later want to modify the focus order, you need to change the controls' TabIndex property values."
I hope this helps.
