Research>Credits exploit.

[Santrega]

You don't need to get research at all and you get somewhere around 180k credits for it... Some people get more, some people get less... This is absolutely a bug. they wouldn't have made the game give you "10k credits per research" if they are going to give you so many credits for nothing...

Is it possible to spend credits after finishing the game?

I really don't want to restart the campaign for achievements.

Luckily, i saved the game right before char. After char I don't believe you can spend your credits, however, just before char if you have it saved there, you can do the missions and spend them. Really any point in the campaign will work... but I found it easier to do the other achievements working with the saved point just before char.
