Tiling Small Space by Patio Door

I put in a dri-core subfloor on top of the concrete in our walk-out basement. I would like to put in a small tile rectangle entryway in front of the patio door using avaire tile (about 9 feet wide by 3 feet deep). The dri-core raised the floor about an inch, and if I put the avaire tile on top, the ending floor height would be higher than the bottom of the door than what I would like. I plan to cut out part of the dri-core for the entryway. If i just put the avaire tile on the concrete, there would be a fairly big height difference between the avaire tile and the finished carpet on top of the dri-core. So, my two questions are:

1) can you recommend some type of underlayment that I can put on top of the concrete so I can raise the avaire tile up a little?

2) if the avaire tile is level with the carpet, will the 9'x3' grid stay in place? Should I try to keep part of the tile lower than the dricore to help hold it in place (like it would be if it were next to a wall)?

Hope this makes sense. Thanks.
