There are many good online learning resources that are well-reviewed, as well as books on the subject.  But as you will see when you start the learning process, there are days, if not weeks, of study required to answer broad questions like these!

mysql> GRANT ALL PRIVILEGES ON *.* TO 'monty'@'localhost' WITH GRANT OPTION;

Question 2:
mysql> UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root';

Question 3: part 1
