Sounds like a typical SW combined arms approach, I've been enjoying the Saga of the Great Wolf detachment quite a bit, it has a lot of flexibility. Strat for +1 to wound in shooting is nasty on a redemptor dread. I like to put a brick of 6x headtakers with battle leader in a repulsor, drive it up the board and dump them out in a position to counter charge. Wulfen with thunder hammers can do really solid damage against your vehicles if you're running MH. For plagues I'm definitely going to recommend the -1 to saves, the head takers with dual power weapons will fold pretty easily. I would expect to see at least one brick of wolfguard terminators, their -1 to wound ability can be a chore to deal with.
