Answer 1

Auto Activation triggers for Java for "abcdefghijklmnopqrstuvxwyz."

Answer 2

Go on

Window -> Preferences -> Java/Editor/Content Assist

In "Auto Activation"
Edit the Auto Activation triggers for Java field for "abcdefghijklmnopqrstuvxwyz."

So pressing any key it will open the auto complete window.

Answer 3

Go to window / properties / facets / include jsf facet 2.

Hence it should give an error saying that you have to put a jsf2 lib.

If you are putting lib point it, in case you are on the server put the disable option if I am not mistaken.

Finally der apply.
