If your going to use hangers against the skirt board here is a little trick to get the floors to match right on. Cut a piece of your new joist and attach a hanger to it then place it up against the rim joist on one side so the top of the new joist matches up with the old one and mark the bottom of the hanger and then do the otner end, now snap a chalk line, then attach with a few screws a 1x4 to the chalk line ( cover the chalk line) . Now all you do is place the hanger on the 1x4 and attach it and you have a perfect line up.
Another way to do this is same idea but just use a cut off of new joist and line it up with the top edge level with the rim joist and make a mark then do the otherside, snap a line, srew a 1x4 and then place your joist in place on top of the 1x4 edge and toenail the top of the new joist and then after they are all in place remove the 1x4 and put all the joist hangers on.
