Now i need to update items in sharepoint list based on repeating table in main data connection. Where and from what should I start. please help!!!

Did you have a chance to look at that link? Basically, your options are: qRules / FormsViewer (my company created these products), custom code or CAML (which is outlined in the link I posted). If you are using Office 365, only FormsViewer will support this scenario.
