Depends on the species. Generally the smaller flatter (fishscale-like)
gemmae can be stored for quite a long time if kept a) wet and b)
chilled. To keep them wet store them between a fold of dampened kitchen
roll and place this in a small ziploc bag. Keep this in the fridge. I
have kept gemmae of D. pulchella this way for up to six months, though
generally the longer the gemmae are stored the lower the percentage that
start into growth successfully. The larger gemmae tend to sprout
regardless of the temperature and will start to grow even when kept in
the fridge. Storage times for this type of gemmae can be little more
than a week at the most.

All that is happening is that as the initial root pushes into the soil
the plant itself gets forced up. You can carefully bury the plant again
once it has formed the first or second pitcher. However, if you bury the
seed to about its own depth when sowing you will find that the tendency
of the seedling to push clear of the soil is greatly reduced.

Not as far as I know. There is probably a convention as to which plant
(the plant bearing the pollen or the plant bearing the seed) is listed
first but I can't remember which way round it is.
