Brian,
Let begin by saying that I generally don't recommend bootcamps. Mainly because the bootcamps focus ONLY on memorization and helping you pass the exam. There is no training component in these camps that focuses on making you a better PM.
However, what you are doing is clever!
You are studying with The PM PrepCast, you are reading the Rita book, you are answering questions from PMStudy and THEN... at the very end of your preparation you also take a bootcamp too boost your chances of passing.
Now that is a strategy that I can support, because you really invest time and energy into self-study, followed up by a sprint at the very end.
You should have no problems passing the exam. And (more importantly) your studies will have a long-lasting effect.
