1. You can google how to setup any IDE, import libraries, export your code to a .jar
2. That is not true at all, Eclipse probably even has more features than Intellij. One of the main reasons people prefer Intellij over Eclipse is because of it's usability. Are you saying usability is a bad thing? Intellij has superior autocomplete, superior indexing and suggestions, these things are beneficial to programmers, regardless of ability.
3. Again, not true. I'm not sure where you are getting this whole "Intellij is harder to use" thing from. I'm not talking about the advanced features, both IDEs have those, and a new programmer won't be using them. At the end of the day, they are IDEs not spaceships. I'm not even sure you have used both Eclipse and Intellij before.
