Since the collections have been updated, it's a question of dragging and dropping the products in the edit collection screen. (grab and drag a square and drop it where you want it)
Sad that the organize button has gone to but we have to work with what we've got.
The cross sells are a bit more tricky to rearrange but doable - have a read through the Collection Types Information forum
