Basically there are 2 solar eclipses and 2 lunar eclipses every year (one about every 3 months -- alternating). Most of them are partial eclipses, and some of them are only visible near the poles, but they happen that regularly.
Every few years one just barely misses one of the poles, so we would only have 3 in that year. Also, because of the exact timing, it is possible to have 5 in one year (3 solar; 2 lunar, or vice-versa).

Lunar eclipses happen about twice a year. The next one is February 21, 2008.
Solar eclipses are more rare, happening somewhere on the Earth every 18 months or so (but statistics show that a solar eclipse is visible over a particular spot every 340 years or so).

They don't -- at least, not by much. Over a period of 5000 years (from 2000 BCE to 3000 AD), there are 11,898 solar eclipses, and 12,186 lunar eclipses. That is about 1 extra lunar eclipse every 17 years.

Generally two of each, each year. But, since a lunar eclipse is visible only over half of the Earth, and a solar eclipse is visible only in a very narrow path, your chances of seeing one without travelling is quite small.
