I would recommend getting what if often referred to as the "K&B" book for 1.4 exam. This is: "Sun Certified Programmer & Developer for Java 2 Study Guide Exams 310-035 & 310-027" by Kathy Sierra and Bert Bates.
It will explain the topics needed to pass the exam. Not sure about your first question but K&B mention you do need to know about Wrapper methods you mentioned.
Taking the mock exams helps. Search this forum for mock exams and the FAQ to find them.

You should have a look on this link:
Objectives
Collections:
* Make appropriate selection of collection classes/interfaces to suit specified behavior requirements.
* Distinguish between correct and incorrect implementations of hashcode methods.

Don't think you need to know all the methods, but you will be given a scenario and need to know which collection you should use etc.
Do some mocks and you will se what kind of questions they ask for this topic!
(it's important to know this stuff when you do programming at work as well... lot's more useful than some of the other topics, so I would suggest to spend some time learning the topic!)

Good luck with you exam
