when using the %Q syntax at the beginning of a new line code, can it replace the first line name = gets or its just some more fancy option of writing the line 2 code without having to type "Hello #{name}!"

While it doesn't replace the "name = gets", you can use them together like this:
name = gets
puts %Q(Hello #{name})
The benefit of this type of string formatting is that you don't have to escape characters like / \ " ' to include them in the string:
chars = %Q(\/\"'"')
will give you the literal string \/\"'"' which is useful if you have a string that contains a lot of these potentially headache inducing characters.
