The early curriculum is great for building a solid foundation. But it seems very single-minded on getting to abstract results in algebraic geometry. You can easily miss the trees for the forest by doing that.

>Are the books shown in the picrel enough to cover the mentioned topics.
They mostly seem to be selected for being the "hardest" book on the particular subject, which is not always the best. For instance BottTu is definitely not the hardest for anything it covers, but the clarity of exposition makes it a worthwhile read.
>how long would it take
Depends how much time you devote to it. If you spend 40-50 hours a week on studying, and you study efficiently, you could maybe finish this in five years. How much you would retain with no interaction from a mathematical community is uncertain, probably low. It takes years of being immersed in the field for knowledge to really sink in.
