injector questions

Guys can someone explain me injector basics?
what's the difference between different cc like 410cc, 550cc, 650cc, 1000cc?
what is low impedance high impedance? spray patterns?
what is factory standard injectors on base model? when I replace injectors , do I need some computer setup? How long original injectors last? when they need to change?

sites like ebay , many different type injectors sold with different cc values says fit rsx
, and sites like autozone offer me injectors as exact fit but says nothing about cc value or impedance etc.

If I install higher cc injectors, are they plug and drive or need some setup on ECU ?
if I install higher cc or different than factory standard , does it effect fuel economy?

here is the story
Year ago I service changed rotary assembly, since then gasoline smell coming from engine compartment. Last time visited, they told me, very small fuel leak from injector, asked $350 for injector change. ( I assume this price were for set of 4 injectors)
I removed cover and checked it, found out one of injectors has bad clip , very small leak, its not even dripping but cause gas smell. (Have no idea why service wanted to change all injectors , not only one or only clip) changing clips and o-rings with full repair set may solve problem but since this car is 12yrs old , I wonder is it time to change injectors? If I decide to change injectors , what injectors I need to use?
