Using a plastic opening tool, pry open the back case by inserting the tool into the seam and moving it in the gap between front and back panel of the tablet.
-
Insert triangle opening picks into the gaps as you work to keep the back panel separated.

To remove the digitizer, insert and move a plastic opening pick to create a gap between the digitizer and screen.
-
Carefully lift up the digitizer a little bit and insert a plastic opening card to separate the digitizer from the screen.
-
There are two things to be very careful of. The cable from the digitizer through to the motherboard goes through the top section, and could be damaged.

The tabs on the side of the home button are light rubber, which gives the return spring to the home key. The rubber seems less resistant to the heat gun than the glue, so if you're not careful you will end up with a pool of melted rubber. In any case, with this method of removing the digitizer, you may not save the existing home button.

Where can we buy the correct home button?
I'm going to have to say that as far as this guide goes, it's fine... but if it was a novel I'd feel let down. "Carefully remove the old home button and replace with a new one." is very much a litote, and "To reassemble your device, follow these instructions in reverse order." is just a let out.
What about the clean up process before re-assembly?
What's the best product to use to clean the glue away from screen and digitizer?
Is it best to clean the glue off completely and actually buy one of the preshaped glue panels?
I have to say, as far as it goes fine, and for a TV series where the hero or heroine walks off into the sunset and you imagine the rest, fine, but for a technical guide some of the crucial details are absent. Or there ought to be a general assembly and cleanup guide on fixit that you can point to. Maybe there is, but I haven't found it.
and here it is, on the iFixit channel.

and this... albeit for a Samsung Galaxy phone and not a Tablet.. but it helps a little.
