For the few I've done, before laying around the door ways, I've taken a scrap piece of the flooring and used a saw like this to cut the jambs first. I think I bought mine at the borg. I'd just drill with a hammer drill and use plastic anchors to secure the t molding. Be sure to leave that 1/2" gap around the edges, the stuff really does expand/contract. Be sure to fill any dips that are greater than 3/8" deep or any severe dips, the boards will separate in time at those areas. I have an area in my kitchen that the floor joist has movement and needs sister-ed and bridged properly, about ever few months I have to beat those sections back together, planning to get that taken care of in the next month though.
