On the subject of plug gaps, there are some (I'm not one of them) who swear that it's absolutely critical to buy them only from a Toyota Dealer because they come pre-gapped at 0.032" and that 0.30" won't work. I don't care where I buy plugs because I always check the gap anyway. If you don't own and know how to use a set of feeler gauges, how do you even know that they need adjusting or replacing anyway?
