ESR is just what it says, resistance in series with your capacitor. Low ESR is important if there''s a lot of ripple current in your capacitor. The RMS ripple current will cause heating (I^2R) losses in the capacitor, and additional ripple voltage. It will also affect the frequency response of your capacitor.

Yes. For electrolytics, don''t choose a voltage too far above the maximum expected working voltage. As the electrolytic''s working voltage rises, so does the ESR, assuming that the capacitance is the same. So, for a 5V application, a 1uF/700V capacitor performs much worse than a 1uF/16V capacitor. Besides, that 1uF/700V capacitor will cost quite ...
