Piss easy is an understatement.
I've got 650GS so far just from playing the story, (I'm on about the third last mission after 8 hours of story), and not really doing anything different than I normally would.
The only tricky thing will be the hundred or so GS from the multiplayer stuff.
Do it on hard, too. I've played the first mission on both normal and hard and there honestly wasn't much difference between the two, you just take a tad more damage.
