It's good to see a person actually admit to everyone that they are a newbie and not another natural Criss Angel (who in my opinion is a better actor than supposed "mentalist"). So I give you some congrats on that.
Okay, so you are serious about mentalism and mental magic. Before you go blowing your cash on the stuff you listed, purchase the following:
-Practical Mental Magic by Ted Annemann
-13 Steps to Mentalism
Study the material in those two books for at least 6 months. Those two books are the bibles of mentalism and you will need every last bit of information you can get out of them.
After your 6 month+ study, I suggest you look into Sleight of Mind by Harling and Nyrup. This will boost your intelligence on suggestion which is used in almost all mentalism effects. It's companion, The Geist, includes many routines using suggestion.
Next, you are going to want to take a look at some cold reading material. I suggest the following:
-Completely Cold by Kenton Knepper
-Full Facts of Cold Reading by Ian Rowland
Study those two books and you will have something so impromptu on you all the time that it will make you sick once in a while. Very good stuff to know.
I'll get back to you when you are done.
