Just wait a week and regear in the new 5mans + Raid finder, you'll make the haste req easily.
Re: Rotation
As you solar eclipse, refresh IS then SF, one cast before you leave solar refresh them. As you enter Lunar, Starfall then refresh IS then MF. Until you get a lot more haste you'll need to likely refresh them again before you leave Lunar.
Always try to refresh dots while natures grace is still active.
If you get a starsurge procc as you're about to enter an eclipse, its often worth saving it until you're in the eclipse.
