I spoke to you over XBL. But just to reiterate...
The above poster has listed the maps necessary to get all achievements. Weapon packs are helpful but not necessary as some guns are very useful, but certainly not needed. They maps were on sale recently at around £5, not sure what that converts to in your local currency. You'll get a lot of time out of each map, even if you just do the missions; adding on extra time if you choose to leisurely hunt.
I personally handled one map at a time before heading to the next, but this is pure preference. I'd recommend just picking up the maps as you go.
I personally really recommend Vurhonga and Mississippi (although the latter has no achievements, I do enjoy raccoon and Gator hunting). Cuatro and Parque are alright although the achievements are a chore. Not a massive fan of Med-ved, with a general consensus in the community that it's a harder map to hunt. Silver Ridge is very friendly as it's very open with some good vantage points, and it's a pretty easy DLC in terms of achievements.
I do like it when the red stuff comes out.
