Weekly 3 and 4 are completely optional.

Depends whether you want to get the 3 screws from World 3 quest and 2 screws from world 4 questlines (since after clearing the world 4 weekly quest, you must also do the 4-4 quest and the 5-2 S-Rank twice quest)

Personally I don't really like doing them all that much cause of the cost and the time it consumes. I only do them when I feel like it, but mostly only do the World 3 one while neglecting World 4.

Yes if I did them every week those extra 5 screws may have helped me one way.

World 3 Quest requires you to either do World 3-5 for consistent way of getting to the Boss (cheapest way is the 1 CL 5 DD route but then it tests your patience since 1 CL 5 DD is squishy), or you do World 3-3 for an easier time but then you need to use something more expensive and pray you get to the Boss node as there are chances of going Deadend.

World 4 Quest is doable with 6 Submarines in World 4-2, but since it's 12 kills, and route to boss isn't exactly stable (if unlucky you can go off-route several times), it tests your patience as well and may require several attempts. The other two quests that come after this isn't too hard however, but in the end you only get 2 screws.
