That sounds perfect for me, even though I really don't care much for Superman.
Anyone know when he started on AC and if any of it has been collected in TPB yet?
As with most things DC, it's quite complicated.
When Infinite Crisis ended, there were two Superman titles. Action Comics and Superman. Johns wrote Action Comics and Busiek wrote Superman. These crossed over for One Year Later. It's a good story and it's drawn by Pete Woods. It's called Up, Up and Away. You can get it in TPB.
Geoff Johns begun his proper run on Action Comics beginning with #844. This is the first part of Last Son, co-written by Richard Donner and drawn by Adam Kubert. IT HASN'T FINISHED YET. It went to #846, skipped ahead to #851 and then #852 was supposed to be the conclusion. But it was delayed because Kubert is so slow. And it's still being delayed. It's supposedly coming out as Action Comics Annual #11 in April. This arc won't be collected in trade until it finishes... which will hopefully be sometime soon. I presume Action Comics Annual #10, which came out during Last Son, will also be collected in this TPB.
Because of this delay, there were a couple of fill-in issues. Johns then picked back up at #855, with Escape From Bizarro World, a 3 part arc drawn by Eric Powell. This was pretty fun. I saw a trade solicited which comes with lots of old stuff, but I don't know if it's out yet.
Finally, the current arc is Superman and the Legion of Super-Heroes. This begun with #858 and the conclusion is in #863, which should probably be released soon. This is drawn by Gary Frank of Supreme Power fame and it's pretty neat, though very confusing if you don't know anything about the Legion of Super-Heroes.
There's going to be a one-shot about Toyman and then we're getting into some big Brainiac arc which is supposedly going to lead into some massive Superman/Action Comics crossover at the end of the year. It's the 70th anniversary of Superman, so that's why DC have got all these plans for him (and they've got Johns, Robinson and Morrison on the Superman comics).
Personally, I don't think you're going to be able to get into it. Geoff Johns' stuff takes a lot of hard work, and unless you're willing to spend the time researching and getting to know the characters and persevere with the story, you're not going to like it.
