Not but seriously like the others said your best bet is use round up. If you still think it's to dangerous for your backyard, go ahead and spend 1000$ on tarps to cover everything for a week to let everything die.
That yahoo answer would simply not work well, to start cutting a 3-4" height, to let the grass grow longer and eventually choking the weeds. Because it seems you don't have any grass to start off, and re-seeding would not work, seeds would never be able to germinate with all those weeds.
Seems you have a lot of thatch & debris, once you have killed all the weeds, it would be your #1 priority to add a good 6-8" of top soil.
