You should just mark your mounts and bolts with a paint pen, should go back fine.
The 2 special tools for this are the counter tool T10355 and the 'thrust piece' T10368. Snap on is only place I've seen the spacer, got my counter tool from Neuspeed for about $80.
I'm going to tackle this tomorrow, wish me luck.
Edit- this is another link for the most of the job:
The counter hold vw tool will not the let the pulley move when taking the crank pulley bolt out if used properly. Do not remove the small pin on the cylinder, only the big clip once you have new tensioner installed. I can't help you with the tdc marking since I actually had two marks notched on the pulley, so look at it very closely.
One person holds pulley and other removes bolt? Possibly without air tools?
