Aren't you a little embarrassed to be asking questions like this when you've passed the exam? Surely you should be answering them now.

An IDE should save you time and make things clearer. If you're studying for certification then you won't benefit from some of the snazzy features of an IDE. Things like code completion will speed up the coding you do, which should be everything anyway when you're studying. I'd recommend you go for a Java-specific coding editor like jEdit, you still have to code everything but it's less painful and quicker to write the mundane stuff.
Look at how JavaBeans work. All properties are encapsulated in getXX and setXX methods. Whenever you see a getSomething() method, you know it will simply give you the Something property on the object. Any calls from there, eg xx.getSomething().runAway("fast"); are methods on the object that getSomething() gave you.

Yes, anyone can create their own JDK. Sun lets us see everything so that we can all learn exactly how their technology works.
I encourage you to stay away from obfuscating. Java has grown because of its openness, it would be counterproductive to the community in general if the idea of hiding source code became the norm. You are biting the hand that feeds you.

The browser is responsible for its own JRE, most browsers will either have their own implementation built in or will have an option for the end user to specify the (local) location of a JRE.
