The best thing you can do is provide good conditions and wait. Bright
light, fairly high humidity, and appropriate medium. Higher humidity
will result in better trap formation.

No, the leaves perform a valuable function by photosynthesizing, and
cutting them off will just weaken the plant.

Give them the brightest light you can, and you will get the best
formation.

As long as the leaves are not getting burned, good light is not going to
make the leaves die off any faster, and will probably result in better,
more robust growth. A good setup I have seen is flytraps grown in large
tubs planted to about 10 - 12 inches below the rim, stood in full sun.
The high rim above the medium keeps more humidity in and still allows
full sun. These were some of the best plants I have seen.
