Answer 1

Once you are able to parse those strings into a Date object comparing them is easy (Using the < operator). Parsing the dates will depend on the format. You may take a look at Datejs which might simplify this task.

Answer 2

If you are also using jQuery ui, in particular datepicker, you can use $.datepicker.parseDate(format, string) to turn your date strings into a JavaScript Date object, which you can then compare using the standard < and >
