Hi Jeffblue,
Congratulations on your new mattress 
As you know I think you made a great choice and there is great flexibility built in to the layering combinations and/or exchange option as well if you need to do any fine tuning.
I hope you have the chance to share your feedback when you receive it.
Post #89 here has information about the pros and cons of the different types of mattress protectors that may be helpful.
