I'm lost in paragraphs 7-9 of Tutorial 3: Detecting and Removing Actors, and Making Methods. Besides the remove object method, I don't get how anything in those paragraph's and the corresponding code applies to the program. I tried hard to understand, but I don't think the author explained thoroughly enough. He didn't explain what the return value is. Any help would be greatly appreciated because I'm stuck.

You may want to check out the Java Lesson on Classes and Objects which deals with creating methods. Maybe you will understand it better after that.

I guess you're referring to this bit:
Note that we're not only calling the method, we're doing something on the left-hand side, too. This method returns something (the object underneath us, if there is one), so we need to store this return value ready to use it again
The return value of a method is the value which the method returns. Some methods don't return anything, but others do - for instance, getOneObjectAtOffset(...) returns a reference to the object it found (if any) or null if there was no object. Having a reference to an object means you can then do things with it (call methods on it, use it as a parameter to other methods).
