I mostly agree except that I do use the two 10-token refreshes each day in all of the shops, and I use the additional 50-token refreshes each day for the guild shop only in search of stamina. That second part is debatable, but I think it is good to use the two cheap refreshes when you have over 3,200 tokens or so for a given shop, because that is usually the minimum for one of the complex gear items we mentioned. By doing that you are likely to hit the good gear more frequently. I can think of at least six or seven or perhaps more items that require 250 to 350 annoying scraps to farm.
I have found that it is better to use the refreshes after the final game refresh of the day, as that gives you the most chance to build up tokens and purchase an important item before it refreshes again the next night.
