I won’t compete with your gear list but I will try to help you complete it ;) Here is how you can break down your gear list(you don’t need to put the cost)by putting items into categories with their weight is essential, Jamie Shortt’s List ,and here is a trip with photos that Jamie did with a 25L pack My first sub 5 lb trip! (several other people show photos and give gear lists in the thread as well),so hopefully this might help you a bit to visualize what you might need.
Here is some general info for you to look at

You could make toothpaste dots like Mike C. shows or there are Archtek Toothpaste Tablets so only bring exactly what you need in a snack size bag for any given trip instead of a whole tube and THESE are good for little thing like pills, toothpaste tablets ect. so you are not packing a whole bottle(you can also get them very cheap at most pharmacies) .
