natural selection still applies, because the people with defects affecting life-span and physical appearance are still unlikely to live to the age where they reproduce or attract someone to have children with, but it is less relevant, what I like the idea of is that a few thousand years down the line,we, Homo sapiens sapiens, will have evolved, in Africa they may evolve to deal with heat and disease common to their area, in Europe I believe it will be less drastic/more slow, but it is an eventuality nonetheless.
No, we're becoming measurably taller and more intelligent. Unless intelligence eventually leads to some species wide madness, I'd say we're making progress.
As for the interference of modern medicine. Well, in a few years we'll be able to create a human with no genetic defects. One day, it might be considered criminally negligent to allow a child to be born with crippling conditions. There does exist an opportunity of abuse here though, as the rich would obviously have access to the best genes.
The only real worrying development is of bacteria becoming increasingly resistant to anti-biotics, but that's not a fault of human evolution.

Evolution isn't a process that occurs purely on a biological/genetic basis. Whilst 'survival of the fittest' may not apply to humanity as rigorously as it once did, there's certainly a technological and cultural component to evolution that's taken precedence in the last couple of centuries.
Although looking at cultural change, it seems occasionally you could argue the case for devolution, yes.
