This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
The best suggestion for tools is to download Sun's Wireless Toolkit and play with it for a bit. (Personally, I use my regular IDE for coding and then integrate through WTK to do my testing.) It should accomplish the basic tasks you'll need for learning Java ME.
The only outside source I used for my prep was Beginning J2ME (3ed) from Apress - I had a copy of Whizlab's SCMAD simulator, but ended up finding it something of a wash while preparing for the exam. My flashcards, targeted to the areas that I felt weak on, seemed to do better by me.
