Answer 1

Have you checked Windows -> Preferences -> C++ -> Editor -> Content Assist -> Advanced and see which proposals are checked off? For the most part that is the place that controls the autocomplete functionality in Eclipse. You may also try hitting Ctrl + Space and see if a window opens asking if you want to turn Autocomplete on.
