Assuming your list reads from bottom to top, it sounds like you're okay.
TT on top is a no-brainer, and amp on the bottom makes sense, as you hardly ever have to access it, plus it anchors your rack on the bottom and gives it a lower centre of gravity.
If your preamp has a remote, you're okay, but if it doesn't, you might want to switch it with the tuner so you don't have to bend over as much!! :-)
If you're getting the drift, it is about convenience here, not sound quality.
Sound quality will be determined more by the weight/mass of the component stand and whether or not it is fillable (dry sand, silica sand, etc) AND the proximity of the components to your speakers. Vibration will be more of an enemy than the proximity of your components in the stand, and that is a whole other subject!!
