Looks like your making great progress here. Grain on the headstock face has popped nicely. The marks on the body look like glue stains to me. I know some forumites have had success in using a product called 'Goof Off' to help in removing excess glue stains. Looks like some more light and careful sanding required. I've managed to remove glue in the past through very light wire brushing.
For Wudtone, the wood will have some bearing on the final outcome of the color. I've used azure sky blue over basswood and it turned out more surf green due to the underlying green tint in the wood.
