Just a few other quick things on doing the brakes
I just changed the pads front and rear on my daughter's Jetta this past weekend. I'm used to working on American cars and there are a few other things that you should be aware of. The bolts that you remove to get the rear calipers off are only about 1" long (The head is 13MM), you need to put a wrench on the slide bolt to stop them from turning as you remove these bolts (I think it was a 15mm wrench, or maybe 14). Normally, I clamp off the hose going to the rear caliper when I screw the piston back in, but I just could find a pliable rubber hose to do so so I just went with opening the bleeder valve as I screwed the piston back in. Being as that VW recomends flushing the brake fluid every 20K miles that is a good time to do so (they tell you to use DOT4 fluid, there have been previous posts where the newer synthetic Low Moisture Absorbance fluids are ok too, they say they meet & exceed DOT4). You definitely need a tool to screw the piston as it is compressed back into the cylinder.
If you do the front pads as you do the rear be aware of one thing. Only the front driver side inboard pad has the wear sensor. If you look at the other 3 pads they all look pretty much the same. They are not. The retaining clip for the inboard pad on the passenger side is just a tad bigger than the outboard pad retaining clips (as I found out the hard way). If you install that pad into one of the outer pad slots it will not fit quite right and you will not get the slide bolt holes lined up. There are plastic protector tubes around the front slide bolt heads, the plastic end to this tube pops off to allow access to the torx head slide bolts.
