Answer 1

Try

 settings[empDept] = { // etc

Answer 2

Try it like this:

var empdept  = 'financialDept';
var settings = {};

settings[emdept] = [{
    'name'       : 'bob',
    'sname'      : 'the builder',
    'age'        : '8',
    'req'        : 'yes'
}];

Answer 3

var o={key:value};

here only value may be a variable, not key .

what you can do is this:

var empdept = 'financialDept';
var settings = {};
settings[empdept]={name:'bob',sname:'the builder',age:'8',req:'yes'};
alert(settings.financialDept.age);

I removed the extra array so you can access the value as you described (not settings.financialDept[0].age as in your example)
