If you are currently doing a quest that involves any of the items in the collection, do not assemble it ahead of time. You will usually get a quest to do so at the end. If you assembe it before you get this quest you well need to collect any missing items again before you can finish the last quest to assemble them.

On the other hand, if the collection has nothing to do with a current quest, it probably does not matter because when you start the quests for the collection you'll need to find them all anyway.

That said, I have my own rule. I never assemble a collection the first time until I get a quest to do so unless I have at least 2 of every item in the collection. That way I know that I'm not shooting myself in the foot by collecting it.
