Amit,
I think you have the correct concept, but you would need to correct your DP subroutines for them to be able to utilize the values retrieved from Excel. Please see my previous post for the same.
I would also suggest you read more about Descriptive Programming. Dani of AdvancedQTP.com has written a book (Scripting QTP) which you can download for free and is a very good source of understanding different ways of working with QTP Scripting.
