Answer 1

When using h:datatable, create a bean method and call this to determine the style. Perhaps this could also be done for a rich:datatable?

    public String getStyleSelectedOrderRows() {
        StringBuilder sb = new StringBuilder();
        String[] oddEven = new String[]{"oddRow,", "evenRow,"};
        int i = 0;
        for (MyObject object: myObjectList) {
            sb.append(object.isSelected() ? "selected," : oddEven[i++ % 2]);
        }
        return sb.toString();
    }

and in the .xhtml:
