?Injector replacement?

So I have injectors 1,6,2,5 making bubbles. Im calling about replacements now with Cummins. They have re-man and new.
So questions are:
1: So Re-Man or New. If Re-man are there certain brands that are safe/more reliable than others?
2: Should I just get the 4 or just do all 6. (I'm broke either way, so "whatever you can afford" doesn't help me as I really can't afford it in the first place, but doing something twice and being down again not making money makes things even less affordable, ya know) Its been my experience in the past that mixing new with old usually make the old go bad. Like doing a top end rebuild on a car and it makes the bottom blow out. So will only replacing the 4 affect the remaining 2?
3: Is there some kind of programming in the ECM that needs to be done after replacing 1 or more injectors. I watched the injector video but did not see/hear anything about using insite or any other required programming. 1 shop said they could put them in, but it would still have to go to Cummins to be programmed.

What engine we are talking about?
870, 871 doesn't need Insite programming but 2250, 2350 does
Always better new nor re manufactured.
Replacing partially will not affect or destroy engine.
