Give more hay. Rabbits should pretty much have as much as they want.
The pellets depend a lot on the individual rabbit. Breeding rabbits as well has high energy ones, and outdoor rabbits have different needs than indoor, spayed or neutered rabbits. For the average pet, you would want 16% or less protein and 18% or more fibre with about 1.5% fat. Manna Pro has some different formulas, some would be more suitable to pets than others. You should limit pellets. The amount depends on the rabbit, but the general rule is about 1/4 cup per 5 pounds of body weight. Some do need more, others less.
I am not sure about the treat or the log, but I doubt they are really good for rabbits. Good treats can be small bits of dried fruit, berries or fresh veggies. Most treats sold in pet stores are no good for rabbits as they tend to have poor ingredients (seeds and nuts), lots of sugar or other issues. A regular wooden log house would be better and is safer if chewed. Any treat should be limited (fresh veggies can be given more), 1 or 2 small treats a day is enough.
For veggies, leafy green ones are best. There are quite a few lists of safe and unsafe veggies, so consult them to see what you can feed. I like to give parsley, cilantro, romaine lettuce and bok choy. Remember to introduce any new food slowly and do it one at a time to avoid upset. Limit fruit as they are high in sugar. Berries can be good though, but not too many at once.
Young rabbits do have some different needs that adults. Up until about 6 months for most breed, alfalfa hay and pellets are preferred. After that, timothy hay is better and a timothy based pellet can be a good idea. Alfalfa has more calcium and other nutrients that are good for growing rabbits, but can be too much for adults.
