compatible with pump in style advanced?

Yes, I'm using them with my pump in style advanced pump, actually, as I type this  Haha

Do the yellow Medela brand valves and Medela white membranes also fit this product?

So far all of my Medela products have been fitting perfectly with these. Valves and membranes included!

Does it state anywhere on the breastshield that the size is 25mm? I use different sizes for each breast so I need to know which is which

Yes it does! I use multiple sizes so I depend on that as well :)
