You don't need to purchase the Naniwa or DMT 8 stones at this point. If you str8 razor is coming from SRD it is already shave ready. Your razor shouldn't need re-honing until at least 6 months to a year after you purchase it, epecially if your paddle strop already comes with some diamond spray to help maintain its sharpness.

As for the modular paddle strop...Consider ordering an additional leather pad--in case you nick the one that is part of the package when you are stropping.
