There's no point in the top bolt being horizontal. Just put it in vertically and chuck a mallion and rap ring on it. The lower bolt needs to either be horizontal or have it's own mallion to let the rope run straight through).

Equalization doesn't matter. Loweroffs will never be loaded past 3kN and a U bolt probably holds 30kN. The second one is just backup in case you fuched up placing the first one.

Welcome to the reality of establishing routes with proper hardware. It's fuching expensive, so make sure the climb is good enough to be worth it.

Nope. In hard rock you can use expansion bolts and those Fixe hangers with captive rap rings. In soft rock, the standard is U bolts or ring bolts with mallions and rap rings as needed to prevent wear. Either way will be more than twenty bucks.
Why would you install gal hardware in 2019? If it's worth bolting, it's worth full stainless so that some sucker doesn't have to go back in 2035 to fix your shoddy work.
