The DME should be fine, but I don't know about the others. 4 months is a pretty long time. In the future, you should know that it's ok to put the hops in the freezer. They'll last longer than in the fridge.
On an unrelated note, is this an extract batch or is there a grain bill that you haven't mentioned? I ask because to my knowledge there is no point in using rice hulls except when mashing.
If you need me, I'll be out behind the woodshed pounding Grolsches.
