I hear ya on taking it apart more than needed. Only had to do it completely once. Took about 15 minutes beginning to end with sort of taking my time. Had all the tools laid out first. Prying off the LCD retainer is tough (at least it was for me) for the two bottom clips.
Then, however, the front bezel had to come off 2 more times cause I didn't want a spec of dust or a smudge on either the LCD or inside of the front screen (too picky).
One note, I didn't disconnect the LCD ribbon cable and remove the LCD. Some of the other instructions hint at removing it (by showing it disconnected and removed). I didn't think it was necessary, you just have to be careful as it is only 'hanging on' by the ribbon cable. If you hold it all together, be careful and keep conscious of it, there's no issue with not removing/disconnecting it, IMO. Just one more thing to break or do wrong if you do. YMMV.
HTH.
