During reassembly, it can be difficult to get the clips back into the body. I found that I had to put two (sturdy) metal spudgers on either side of the lower-right clip in order to gain enough space to get the clip into the body. Even then it required a fair amount of force (obviously not so much as to damage the display).
The display data cable may be glued into place along the right and top side of the right battery. You should use an iPod opening tool to pry it away from the adhesive. This will allow you to get a wider opening between the display and iPad body in order to access and remove other cables.
Two opening tools make this process much easier allowing you to move progressively around the LCD while separating it from the frame.
Not all replacement displays will have film over the GPS antenna.
Is it necessary to remove the tape from the LCD? My replacement front panel did not include the tape. I therefore left the tape on the LCD and it worked out fine.
