Should I go with the Timberlok wood screws, or run a lag screw all the way through? The posts are dried, and the deck is dried as well. But there is a chance I may have to do a few posts using brand new (wet) 4x4 posts.

They leave a residue that impedes air-flow, costing you money. Clean the ducting in the last six months? 17,000 dryer fires annually!
