Hi,
Eviews is not real hard for you as it does not need too much code.
I suggest you start with simple one or something you real need in your thesis or project you will do.
I guess you just need a few parts of Eviews functions rather than all, so the Eveiws guide and some tutorials slides from Eviews web will suitable for you.
Guide:

tutorial :

When you know the basic, you can research what you need in the web or buy (or borrow) the professional book if you need.
Hope this can help you
Regards
