I don't mean to say you are trying to be dishonest, knowing the counter is one thing, why the need to reset? I just wanted to point out that reseting counter (if possible) have no effect of making your gear any newer. But if you are talking about replacing your shutter mechanism, yes, that is possible, but unnecessary till many thousand shots later.
Upgrading of lenses and all have no effect on the wear and tear of your shutter mechanism. Worry less about such stuff and just have fun shooting.
