I think there's no best way. There are two important things to consider when it comes to layout. The first most important thing is consistency. Pick an approach and make sure that the entire team agrees and applies the layout. Secondly, if your class gets big enough that you are searching for where those pesky properties live (or have to implement regions to make them easier to find), then your class is probably too large. Consider sniffing it, and refactoring based on what you smell.
To answer the reshaper question, check under Type Members Layout in Options (under the C# node). It's not simple, but it is possible to change the layout order.
