Answer 1

You can set the year range using this option per documentation here http://api.jqueryui.com/datepicker/#option-yearRange

yearRange: '1950:2013', // specifying a hard coded year range

or this way

yearRange: "-100:+0", // last hundred years

Answer 2

Actually your first piece of code is working correct. This is the default behavior of datepicker, check this demo and code.

min: current year -10 (2013 - 10 = 2003)
max: current year +10 (2013 + 10 = 2023)

However this can be cahanged using the following option.

 yearRange: "-20:+0"
