By the dates you have given then you have not exceeded seven years yet, but you are leaving it very close. So I believe your ATPL exam passes are still valid, the single engine IR still keeps that active, so that gives you until Nov 2017.
The thing about doing the entire rating again after three years was only a recommendation and it is the discretion of the ATO what training you need to do; though over 6 years you can't dispute the need to do more than the three sessions.
Well any decent school would suggest you do one or two training flights to see where your level is and derive a training plan from there, I hate to say it but over 6 years then the amount of training may not be insignificant.
