Even if you break a couple plastic tabs, you'll still be able to close it up, but try your best not to or it won't close as tight as before! A few tips based on my experience with it:

I used plastic prying tools for most of it because I was really afraid that I might scratch the case if I used metal ones, but in retrospect the metal ones would have worked better.
2) During the prying, some of the clips may shift out of place and need to be repositioned. There is one clip in particular near the USB port that shifted out of place and couldn't be pushed back - I had to unscrew and lift up the USB circuit board, reposition the clip, and then put the USB board back. When properly positioned, the top ends of the clips should be a little below the level of the case edge - not raised above it! I wasted a good deal of time wondering how the case was going to close up before I realized this.
3) Be really careful about how you disconnect and reconnect the cables that connect the glass and digitizer to the circuit board. Tech Republic had the best instructions on this in my opinion.
4) Depending on how shattered your glass is, a pair of tweezers to remove little pieces may come in really handy.
5) I used a pair of latex gloves to handle the glass to make sure I wouldn't leave fingerprints on it. I picked up a box of 4 pairs in the pharmacy section of Walmart for 97 cents.
6) I used double sided tape to secure the glass to the frame. I laid it down in strips on the plastic mounting frame, laying each one down first and then using a scissors to cut it to size. After laying down a strip of tape, I peeled the tape's plastic backing off, so that only the adhesive remained on the mounting frame.
7) When you put the glass onto the adhesive, make sure you don't forget to put the
power CENTER button in place and that you position it correctly. The adhesive is going to hold the glass on really firmly, so you don't want to have to take it off because you forgot the power CENTER button.
