I just played my first match on both Sanctuary and Foundation which were released this month for the XBOX 360 as part of their premium service. I decided to record both games so everyone could get a sneak peak at the maps before they come out for PS3. I believe they'll both hit the PS3 sometime in May for Premium members.

I thought both maps were pretty well laid out compared to some of the other DLC maps that have been released for MW3. Since there seems to be a lot of cover on both maps I think the Specialist or Support strike packages would probably be ideal. As you'll see on Sanctuary the map is so large that I wasn't able to use my Reaper properly to get kills.
