Whenever I research a topic to learn about my deen, I have to look into multiple chapters and verses without any specific order. So, never found the order of revelation to be relevant. Think about it like ,mmm, may be the bill of rights, or constitution. Even though its organised in an order, the wisdom is spread throughout the book and one needs cross referencing within the Qur'an to try and understand it. The order of compilation provides contextual meaning to many things, like stories or phrases made of multiple verses. Other than that, there is no specific way of reading. If you read all of it, it should be fine because you can cross reference and draw logical conclusions from the relevant ayaats.
