So I'll try to do it myself and consider the NRW filter (assuming the engine isn't toast, I'll be doing well to get away with this twice !)

spammysandwich sounds right, I think you're at high risk of losing money.
We don't know the dynamics of these injector failures, but we do know that when one fails, others do follow.
One thing that is remarkable is that we don't hear much about injector failure leaving the engine alive. It's like lottery odds, if you won it once (your engine is fine after first inj failure, supposedly), you obviously shoudn't throw the entire prize in the next game.
My suggestion: stop the car, get 8 new bosch injectors (including the first one you changed). You can find it in links posted above.
Maybe inspect for wall scratches/bent rods? I don't know, I think you will need a used engine if something bad has already happened, so let it live, hope for the best.
Don't try to start engine without solving the issue. That's what killed my engine (I was going to be one the lottery winners if I didn't, because I got my hydrolock from that).
About the filter, we don't have proofs of its efficacy in the injector failure prevention, but it's so cheap and logical that we just can't figure why not.
