Answer 1

I think this is what you are looking for:

• How to: Obtain an X.509 Certificate
• Makecert.exe (Certificate Creation Tool)

Answer 2

I prefer a tool written by the guys over at plural sight. It allows you to make a cert and store it directly into the windows key store of your choice or a pfx file. It is all GUI based and a lot easier to work with then make cert.
