As I've said before, you need to use the search facility. There are a number of key items missing from your list, (CPL for example, Exam fees, test fees, licence application fees). Plus, you are assuming you'll do everything in minimum hours and that the price of avgas will stay constant for the next 2-4 years.
Just to give you a hand, try looking at the Integrated vs Modular thread at the top of the forum.
