I would write those styles like this:
The styles in blue above are probably redundant and can be deleted, as they are the defaults anyway. Only use then if you are overriding bold and/or no-underline declared earlier on (which is unlikely).
You don't need to repeat styles on the :visited pseudo class, as they will be transferred anyway. And the :link on the <a> is not normally needed.
