Does Amazon allow separate providers for each territory? I understand to be a provider you must own trademark for your territory.

You have to see how much gross profit and net profit is there in the product sale. Let's assume the net profit is X then you could ask around 15% to 20% of the net profit. It also depends on how much efforts you are doing and who is paying for the paid ads. It also depends on how much efforts client is doing to build his brand on social media and other channels because if he is doing efforts, there will be more sale of goods.

A good starting point for determining valuation is 3x your annual profits. That said, you may find a 1 - 2X variance up or down depending on the type of product(s), the category or categories you sell in, your total number of SKUs, etc.

There are plenty of experts within the FBA field, you can Google them or seek help here on Clarity. Before you seek help, perhaps you want to look into these marketplaces and check for entry requirements and market research. For instance, you need to register for VAT to sell within the UK. Check out the UK government site for more details: https://www.gov.uk/vat-rates You can seek help from accountants over at ukvat.uk.com instead of the big 4 as bigger firms will take longer time to get back to you. As for EU marketplace is simpler once you have applied and started selling within the UK marketplace. Germany now requires sellers to have VAT as well. Selling within the Japan marketplace is pretty straightforward. Keep in mind you will need to translate your product listings when selling to non-english countries. You can easily hire a translator on Upwork.com and make sure the freelancer is fluent in the native language to avoid any direct translation mistakes. Every country and marketplace that you choose will have different rules and regulations so be sure to check them carefully. Stay laser focus on the marketplace you want to expand to instead of trying to sell within all of them. Get familiar with one and generate sales before moving onto the next. If you need more help selling within the UK marketplace, I am happy to help out as I have clients selling within US and UK marketplaces.

Yes; if you do a presale, those buyers will get the book immediately upon release. Include a message in either the front or back matter that encourages them to leave a review once they finish the book.

Book arbitrage can be a great way to make extra income with Amazon FBA but it's not for everybody. While I don't have specific experience with the program you posted, I looked at the web page to see what they are all about. First, the link opened 10 identical browser tabs which is pretty suspect and feels spammy. Their program is specifically geared to finding cheap books on Amazon that have few or no FBA sellers. You buy the books and relist them as an FBA seller at a higher price then pocket the difference. I don't have any experience with this type of arbitrage so I can't say if it's a profitable method. If you're just starting out, I would go to places like library book sales and Goodwill to find cheap books. There is a big movement right now for college students to find alternative sources for textbooks since they can be extremely expensive. This is an excellent opportunity to find cheap textbooks locally and sell them on Amazon. You make money and the buyer saves money vs. buying from a bookstore. If you're considering buying this program, I would strongly recommend doing more research as there is a wealth of free information out there on book arbitrage.
