Physical Product Design: is there guidance/books on how to focus on only the most essential features that deliver the most value? (80/20...)

If you have international customers who speak other languages, response is lower when you speak to them in English. Solutions like Trustpilot handle that. Have implemented them plus some other methods for international customers in various countries, would be good to know a bit more about your specific requirements and share some tips on a phone call.

Engagement matters most. Engagement is actually a function of great product and great distribution. Engagement is thought-of mostly as a product issue but in many cases, it also expresses itself as a distribution problem particularly where there is no possibility for a "single player" experience (marketplaces, feedback loops, anything attempting to be inherently social) If you have sustained engagement (a product experience loved by users) you will be successful, limited only by the potential number of people in the world that need the experience you provide and growing at a rate closely correlated to your distribution channels. Inefficient distribution is easier to optimize for then insufficient product. So to this extent, product matters more. But available distribution channels (or more accurately, the unavailable distribution tactics) also can define a company's fundraising options, and more definitively, the overall cultural and corporate DNA of the organization that forms around product & distribution. This is the best, most generalized answer I can provide to your question. Happy to talk to you and provide you a more contextually relevant answer to your own circumstances.

Shipping components are expensive and unless you have the volume to buy in quantity vs small bundles is when you'll be able to shop around for a better deal. For example, Uline offers packaging in bundles of 8 or 25 as their minimum, this is stock item for which they order several thousands units of to keep the cost down. For you it fits because you can buy in small amounts at a time. However, if you have a need for 1000 at least or more units then buying from Uline is really expensive compared to what you could buy them for. Uline is a major distributor with a 45-50% markup on their items (give or take) as they have large warehousing and infrastructures. If you are ready to move to the next level, first find the correct material name for each packaging component, and look for suppliers of that particular item. Search websites likehttp://www.thomasnet.com/ for suppliers. Or go through a packaging broker instead of a distributor, like Landsberg Orora, or Ernest Packaging, and they can do all the leg work for you and still save money. Additionally, I know your drawing is not to scale, but there seems to be excess empty air space, if that is true then you can customize your packaging per exactly your needs, which will help to further bring the cost down. An engineer should take a look at your current situation because there is more at play than just shipping components - method of shipping, weight, weather condition, materials thickness etc all play a roll and can all contribute to cost saving while making the whole thing function better. This question is common enough that I've written tutorials on it http://howtobuypackaging.com/how-to-buy-packaging-part-1-determining-your-packaging-needs/.

I have built several multi-million dollar businesses using (2) very simple questions: "What makes you say that...." and "Tell me more...." No matter what someone says to you, you just keep asking one (or both) of the questions. If you do it 4 or 5 times in a row you'll learn everything you ever wanted to know.
