1.) How can i make the workbook open with Macros Enabled - always, w/o
user
being asked for the option to choose - Disable or Enable.

I think you have just considered to decrease the macro/security level to
low, is it true?
Alternatively, if you don't like to decrease the security level, you can get
a digital certificate
for running Excel Macros under High Macro Security.
