This is tough to answer because the number of perches you provide will depend on the size of your cage and the size of the perches. Those perches all look quite nice but again, it depends on the size of your cage as well. Put the perches in the cage and see if you think they have enough, also be sure not to crowd the cage too much, especially since you have two birds. Looking at the measurements, I would probably do at least one more perch, but again it depends on your cage, and it's hard to say without seeing the cage with the perches in it.
As for water, I wouldn't worry about it, unless they start showing signs of dehydration such as being lethargic and weak. Budgie take small drinks of water every now and then and they do it very quickly so it's rare to actually see them drinking.
