I haven't been following this issue for some time. Have the reported statistics of such things as cancers, birth defects and other problems stopped being more of an issue in more or less direct relationship with the proximity of homes to the power plants?
This has never been a serious issue. As far as I can judge this, all such studies are hoaxes. The most recent one in Germany for example, surprisingly disappears if you take into account the correlation between wealth and leukaemia rate. I don't know WHY that correlation is there, but it tells you that PERHAPS your data is biased and you are working like a Texas sharpshooter (i.e. shooting first and then say what you were aiming at). If you look at radiation levels near nuclear power plants you will measure nothing. I've been in many German NPP and if you even so much as have one radioactive dust particle on you it will be noticed and gotten rid of.
Just a comparison: When I visit a plant in N.Germany I will take a 700 km flight and then visit the plant. For such visits, I always carry a film badge dosimeter as we go into the control area, but usually the highest radiation exposure is from the flight (you can check this since you get another dosimeter when you enter the plant).

And have people figured out what to do with nuclear waste? Every time I hear about the places that are "safe" to dispose of it
The REAL question is: Do we really want to tuck it away extremely far away? With a new technology called transmutation, one can get rid of the nasty long-living radioactive products and in 200-300 years, the little waste that is left (simple comparison: if a Western European citizen takes 100% of his electricity from nuclear power, the amount of waste he is responsible for is about half an ounce) will no longer be dangerous and be worth one hell of a lot (it contains precious metals).

I think of things like the Titanic and the BP Oil spill
Accidents happen. Pumps fail. Ships run into icebergs, pipes break. This is the way of the world. Now what's different with nuclear power plants? In modern plants, all parts are available three or four times, and in at least two different ways, so that a systemic failure doesn't fail all alternatives. NPP are designed such that every part may fail without endangering the whole.
This is a different philosophy than that of the Oil industry. They also do probabilistic safety analysis, but their unit is not "amount of severe accidents" but Dollars. They accept big accidents and just try to minimize the cost. The nuclear industry does not accept accidents. Fukushima would have been shut off in Europe decades ago because of the lacking protection against tsunami.
Such risks are evaluated systemically and both in a deterministic and probabilistic way. And if it's above an extremely remote level of risk (similar to the risk of being killed by asteroid crash), something is changed.
What have we learned from Fukushima? When you deal with nuclear power, a safety culture is a MUST. That includes the regulatory body. In fact I would hope that finally the IAEA will watch the national regulators more strictly. It's like the Euro crisis: International regulations should not allow countries to mess up.

and people moving to the Falkland Islands as the place least likely to be involved in a war and other such ... "oops".
Natural events are unpredictable, but their probabilities can be calculated. You can calculate that there won't be a "big one" in Finland (Olkiluoto EPR), but your water intake might be frozen. In southern China (Taishan EPR) there is no risk of a frozen intake, but you might get a tsunami. The design is adapted to take that into account. And of course, mitigation of a severe accident, no matter how remote, is foreseen in the design.
