Good Textbooks for Maths Further Maths and Economics

So, I am starting Maths, Further Maths and another subject (not Economics, cause my school doesn't do it. MAths Further Maths are Edexcel, I was wondering whether that there was any good revision guides that cover the whole courses of Maths and Further Maths.

I was already thinking of getting these two:

However I'm unsure how good these are so wanted to check if they are any good before buying them. And whether I need to get both or just the Further Maths one.

For Economics, considering I can't do the course with my school I want to learn the course at home (not to do the exam, but just for my own knowledge), and I was wondering whether to get this revision guides or something else completely to learn the whole course.
