It's pretty late but..

1. Buster NP double as Buster opener to give bonus to further damage, this is always the case for those weird AAA or QQQ with Buster NP.. especially important when aiming for hard hitting. Even if it's Arts it won't matter much to his np refund, at least that is the case for Gil Caster.

2. Alone it does not make any sense, but it's an reasonable skill once you have the team assembled.. the most obvious is to stack it with Gil bride star up and arts up, otber is like Tamamo arts up that also boost star gain from arts by 50%. Maybe you want to go full passive with Arjuna + Robin..or Hans and Merlin all of those will help you gain  stars in arts team  but for the former 2nd skill is both star gen and crit for the latter it's just massive crit buff. Arts skill are often versatile like that.

3. Same as above, whether he crit or not depends on your team, for Example Nightingale, Gqrcher and Hans will give you 1 :4 : 15 ratio of star weight, effectively making him a crit hitter.. but Chloe, Tamamo, Garcher wil put him as 2ndary star puker + AoE sweeper with occasional crit with it's 3:1:3 star weight ratio. Also you said it yourself his NP Gain ain't the best, he's there for Arts chain mainly.

4.) You don't spam his np but if you do It's for the stars.. however setting up your team to spam NP doesn't worth it IMO.. what should you do is define his role in team and stick with it..

This is why I can't stressed enough that Arts is all about team, most art based servant are subpar alone but as a team they're superior to other in term of versatility.. you're using Buster logic that one skill had to be consistent and arguably only quick perform better solo so the approach by itself is mistaken.

For Buster consistency of skill is vital because they need to aim for highest damage in single burst or at best 3 turns, after that they ran out of juice

Arts doesn't aim for one time burst but rather consistent damage, one way to do it is by chaining NP to crit possibly with as much buff as possible
