1- AC amplifier means that vacuum sensor which increases the RPM when we switch on the AC.
2- Sorry I also dont know the exact term for that paint job, which we see within the wheel-wells, that "textured surface". Benefits: Rust-protection etc.
3- Seiken was the 2nd best option available in the market, and secondly those days I felt lazy enough to get the toyota one from 3s. Ye b theek hai, itna bura nhi
