Don't bother with cams unless/until you are upgrading the turbo.
The Tomei Poncam type B 260/260 are the best for my money although I don't know anyone with an R34 and the Type A. Put it this way, they don't destroy your idle or reduce driveability much so why not go as big as possible?
They are still street cams when it comes down to it, Tomei make the Procams for more full on situations.
I have 255 rwkw with a GCG highflow at 0.9 bar and these cams.
I don't think the cam gears are worth getting although if you want you can sacrifice some idle smoothness for early boost with stock turbo. I think this would equate to top end losses with bigger turbo.
