Yeah, you should decant the liquid on top first. This is often old beer/water you added. Also, a little trub won't hurt anything, but you are obviously only interested in the healthy yeast, so that is why you try to keep as much trub out as possible.
I would let those settle and probably transfer them one more time to get the best yeast samples you can.
