Yes - it self pollinates, and the seeds are ready some weeks after
the flower dies. Just tap the flower stem with your hand or a sheet
of paper underneath - if they are ready, the seeds will fall out.
For many people, too many self sown Drosera are a problem. I usually
cut the flower stems off once the flowers are over to prevent this.
Beware - the bottom flowers on the spike can scatter seed while the
top flowers are still flowering.

I'm only really familiar with U. bisquamata and sandersonii, but I
don't think there'll be good seed in flower parts which fall after
a few days. Normally, the seed capsule (small, roundish) remains
on the plant. Again the seed should be ready in a few weeks.
Test as for the Drosera. These are even worse if they self-sow
in other pots, as unlike a Drosera, they are virtually impossible
to get rid of.

I don't think it will make any difference. I find repotting in fresh
medium every now and then re-enlivens D. capensis.
