You can get them from Toyota, RIPCO, Super Cheap Ripoffs etc..
I paid $60 for my NGK but normal price is around $90+...best to shop around.
But if I were you I would replace the air filter and fuel filter first then the spark plugs and do the leads last because the leads are not cheap.
Or get the non platinum plugs number ngk bkr6ep seeing as your only trying them to get rid of the problem! Buy a set for $20 and they go just as good as platinums for a while - best bet is to replace them every year or so depending on how many km's you do if you use the copper plugs or every 50,000km's for the platinums i think!
Right on the money with the leads dude i think they go for around $170 or so a set retail!
