Best plugs are NGK BKR6. for wires either OEM or NGK. Getting bigger "performance" wires won't do anything at all. I got NGK 5mm wires (oem replacement) because they were blue

as for oil, I suppose Mobil 1 is what toyota recommends. I use Mobil 1, though I was using it before I even knew it was recommended, I chose it because it was the cheapest synthetic I saw in the particular store I was in (which didn't have a big selection btw) but it's really personal preference
