I checked the paint samples you sent over and I think the warm taupe would work best for the living room. It pulls together the natural light from those big windows way better than the gray option. For the trim I would stick with a semi-gloss white because it holds up against scuffs and cleaning much longer than matte. If you go with the taupe you might also consider a soft cream for the ceiling to keep the room feeling open. I painted my own hallway last fall with a similar palette and it made a big difference in how spacious everything felt. The primer coat is really important especially if there is any old dark color underneath. You will want to let each coat dry fully before adding the next one or it can bubble. Let me know if you want me to come by and help tape off the edges. I have a good angled brush that makes corners much easier. Also be sure to cover your floor drops because even with careful cutting in there is always some splatter.
For the bedroom I would go with something cooler like a pale sage green. It helps create a calm space. You can always test a small patch first to see how it looks at different times of day. I can bring over my roller extension pole if you need it.
