I think all what you need is just a new door switch bezel panel with good clips. Clips on your current one seem to be broken.
Or, just a couple drips of superglue.

Wait, I'm a bit lost. I'm not really sure what this epoxy paste will do but here's how I follow it.This is a common problem on the 97-99 Camrys. You don't have to replace the whole door panel. I had the dealer fix this problem for me as a favor some years back on my 98 Camry. Here's how to do it yourself for around $4.
Get yourself some 2 part epoxy and a couple of c-clamps. Remove the entire window switch. Look down in the hole and you will see how the panel has separated a bit. Mix up the 2 part epoxy. Apply it to the where the panel has separated. Now use the c-clamps to clamp this area tight for a few hours as the epoxy sets up. After a couple of hours remove the c-clamps and reinstall the window switch.

I don't think so, because in the guide for taking off the door panel (http://www.toyotanation.com/forum/t145402.html), he takes out the master switch before removing the final door panel...so I think I don't need too...Hopefully Mike backs me up on this one.It'll be easier to work on if you take the door panel off. Then you can get to it from both sides.
