Surround speakers are by nature "ambiance" or "effect" speakers and are therefore by nature less difficult to place effectively. I like your first idea; surrounds should ideally be above ear level, slightly behind, and directed past the listeners ear and not directly at them. You should, as a rule, not place surrounds in front of the listening position. Angling them down towards you may or may not sound good to you -- you should experiment with this. If your surrounds are dipolar or bipolar you may benefit from their output being less localized (diffuse) -- this is especially effective with horror movies, effect sweeps, ambient crowd effects in a concert DVD. These types of speakers are highly recommended for surround duties. Hope this helps.
