I used to run werewolves, I think you should take out overrun, its nice with the +3+3 but full moons already gives you trample and its cost is kinda not worth it. In it's place, in my opinion you should consider or if you can afford it some or your incinerates from maybeboard which could be useful.
The number one problem with werewolves is flying defense, you have daybreak there, which is a great card, but I primarily always lost due to people just flying over, that and people playing two or more spells a turn.
Otherwise you're on the right path ;P
Oh and +1 from me because I love werewolves, and this is a deadly combination, and it scares opponents. Hopefully Avacyn Restored will fix the few problems with them :D.
I always suggest more dual lands if you can get them, a full playset of Copperline Gorge really goes a long way to make your mana consistent, what else to add really depends on where you are taking your deck, I personally like having Corrosive Gale available if I face fliers.
