I have the same setup as you do (PS Antiglare on the screen, Zagg InvisibleSHIELD on the back). I just received my InvisibleSHIELD and it was pretty easy. The trick really is to wet the hell out of the thing.
For anyone that is trying to install the InvisibleSHIELD on the iPad, I'd suggest covering the headphone jacket and the 30mm connector before applying the InvisibleSHIELD to prevent any short circuiting from occurring. I used the entire bottle of liquid that they provided plus some additional soapy water to make the whole thing as wet as possible. I then placed the film on the iPad, adjusted it to the correct spot, then used the squeegee to remove all the bubbles. It's a pretty easy process if you make sure to keep the surface wet.
For the OP, I'd retry it again and keep the soapy water near. I don't think those bubbles will go out during time. I'd retry it and make sure to release all those bubbles.
Here is my finish product. It took me about 10 minutes to get it the way that I wanted it to be.
