Definitely don't start with Resurrection. (I did: mistake! when you get to it you will understand why.
)
It makes the best sense to read them in order. They're a lot of fun. Chris Golden and Brad Linaweaver were my favorites of the collaborators as far as writing style. But my favorite sequence & battle are the last 75 pages of Resurrection. There's just some imagery that begs to be on film. And incredible plot twists, the pace is fast.
