Here's another vote for using both. Like Cutter said, it's not tough to incorporate the DW2 mutations into the D20 Future/Apoc framework. Apoc also has a Template called Viral Deathspawn that are very much like the various movie zombies. Apoc and Future both have a lot of bits and pieces that fit well in DW2. Though I don't have it, I've heard great things about Redline as well.
Blood and Brains and Year of the Zombie also has good material for games with a zombie element.
Lots of options for PA games in D20 Modern.
