Answer 1

Override method onCreateOptionsMenu in your activity:

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuItem menuItem = menu.add("title if needed");
        menuItem.setIcon(R.drawable.YOUR_ICON_HERE);
        // the rest of the code here...
    }

In fact if you are planning to use this action bar on old platforms as well (2.x-3.x), you better consider using ActionBarSherlock
