What's the cost of Living at Kuala Lumpur?

Hi,

I got a job offer from a Malaysian company and salary is around 13K MYR before tax and my office is near Kuala lumpur Sentral. My wife will be a home maker initially till she get a job(she is also an engineer with teaching experience). My kid is in first standard and I am looking for a decent Indian school for her with day care facilities if available. What will be the location I should choose for at KL for a decent stay with some savings preferably closer to office? Medical insurance for myself and my family will be provided by the company. What will be my total expenditure? What is the possibility of my wife getting a job?

Regards
Pradeep
