Looking for learning tools
Eclipse will be fine. As for tutorials, start with all the Java tutorials. You will be way ahead...
I was self learning C++ too before I got in OOP courses at uni, where they used Java.
It helped me a lot, since I got all the OOP fundamentals from C++ first (ie, classes, visibility, inheritance), and since Java is a pretty "restricted" language in comparison, it was easy to learn. You can see if you grab Eclipse (or any IDE that supports javadoc) that everything in Java's standard libraries is well documented, so you can learn a lot by just typing some class, hitting ctrl+spacebar and reading the related javadocs.
I wouldn't worry too much about it. Some things might strike you as odd ( Java's "protected" against C++'s "protected", no operator overloading, no more pointers/delete/derefencing, etc) but its just language stuff that you can learn rapidly as you go.
