The only advice I'd give here is to say that you'll want to focus more on the Renew casts than PoH. In 10-normal a renew is easily enough to keep infest under control, and by allowing you to stay mobile it will make your life far simpler.
LK-10-normal is mostly about being in the right place at the right time, so focusing on your instants makes that easier. That's not to say that PoH isn't in principle better, it is since it allows you to deal with infest in fewer GCDs - however if infest is coinciding with valks or defile (as it often will) then keeping hots up will make your life far far simpler.
Oh and if you have to do the disease then I advise you to bind 'cure disease' somewhere rather than use abolish.
