Hi,
Both answer are No.
Many people have asked about the possibilities of walking from Vindstad to Kirkfjord to avoid the boat. Although it is technically possible you would need ropes and special gears and the terrain you will cross is very dangerous because of many rock fall areas.
For the second part it is (at my knowledge) impossible to walk from Narvtinden to Fageråskaret. The ridge line between Narvtinden and Middagstinden (516) is to narrow and in some places it leave place to big cliffs, especially after the place call "Daumanns dalen". It is also impossible to walk along the north side of "Solbjornvatnet" lake because it is only steep cliffs.
But for this part (Narvtinden to Fageråskaret) if you really want to walk it is possible to go on the south side of the lake (Klokktindryggen and Forsdalen). Although this side is not easy, (there is no path at all) it is possible to walk there without climbing gears. you can find part of the GPX track

Have a safe trip to the Lofoten
