Answer 1

I did it by deleting ".metadata" directory on my main workspace :D

Answer 2

Generally this can be activated by enabling Content Assist. It can be found on Window-Preference->PHP->Editor->Content Assist

1. Setup your php_include_path. Go to the properties of the project. Then PHP Include Path.
2. If you have any external library add it there too (I use Zend and Kohana).

Check your .buildpath, try build something like this:

<?xml version="1.0" encoding="UTF-8"?>
<buildpath>
    <buildpathentry kind="con" path="org.eclipse.php.core.LANGUAGE"/>
    <buildpathentry kind="src" path="src"/>
    <buildpathentry kind="src" path="vendor"/>
    <buildpathentry external="true" kind="lib" path="common-libs/vendor/project-sample/lib"/>
</buildpath>
