I, too, can help you if you come across some stumbling blocks (and you're bound to, trust me :)
I know Java and C and objective-C, but I'm no master at any of them. I know the basic stuff, but even that is plenty and you can do amazing things with any of the languages.
Also, when you're learning Java, make sure to bookmark the Java API http://java.sun.com/javase/6/docs/api/ as you'll be using that a lot. Also, get a decent IDE to help you on your way, Eclipse or Netbeans are IMO good choices and both are free.
