The simple answer to your question is: yes, it's that simple. Just connect the VGA port on your laptop to the VGA port on your TV. Two things to bear in mind:
1. There is probably a key combination on your laptop that will make the laptop output to the VGA port. It's usually 'Fn' and something. Often, if you toggle it, you get laptop only, TV only or both.
2. There is probably a menu item on your TV that you need to select to cause it to 'see' the VGA port.
Don't worry about all the other video stuff - you should be fine.
