As you swing a lot faster forward than upward -- I've rarely seen pros going beyond 30 degrees of swing path prior contact, including Nadal on clay -- you'll get more spin that way.
I do not agree. If you close your racquet face without changing anything else you'll just hit the ball lower over the net, or perhaps into the net. This is my experience as a player, and also what I would deduce from physics (I have an Masters in Mechanical Engineering).

If you want more topspin you need a greater vertical component in your swing. Open or close the racquet face to get the appropriate height over the net.
