q1: on the lecture notes, it says nodes in B+ trees have up to b children. How shall I choose the b value for my program?

A larger "b" generally leads to fewer levels in the tree and faster operations, but it may increase the cost of splitting and merging nodes. You are recommended to start with a b=3. Once your program works, you can try different "b"s, but in general, b should be greater than 2.
