Well, after being pulled away from this job to work on other things, I was finally able to get a little work accomplished this past weekend. I now have a big chunk of the backerboard laid into place. Also had to disassemble the bathroom sink and toilet and remove the closet flange. I'll install thet back once the tile is in plcae so I can get it installed sugly against the tile.
A few days after laying some of the backerboard, I was walking gingerly acrossed it and noticed a little gritty feeling underneath it in a couple of small areas. It seems as though the thinset underneath it is broken up a little bit and not providing much (if any) adhesion in these areas.
There are 2 or 3 areas about a foot in diameter that are like this. I wouldn't be worried about them if they were located underneath where the couch or the refrigerator are going to be, but these are right in the middle of the pathway leading to the garage door.
Should I pull these pieces of backerboard up and reset them (or new pieces), or can I just disregard them. My thoughts are that the gritting will just get worse, but I'm always open to new isdeas.

You could drill some small, maybe 1/8-1/4" or less, holes in each area you think are problems, and use a 10-20cc syringe to shoot some thinset into the space. That's what I'd do. You want a "slip-tip" style syringe.
