Yea yea, I am stingy with the cookies. That shift+refresh will get you every time. Better luck next time
Well I have a porter 890 IIRC, so if the base plate holes are the same I'll lend you the bit and the plate. Otherwise you could order a plate from Rockler, the plexi plates are not too expensive.
Looks like you may be in luck, I found this on Rockler:

I recently purchased a Porter Cable 892 router. The base has a large diameter opening, so if you have one and want to use template bushings, you'll need one of these. The hole pattern is the same as the 690, so it is a perfect fit.
As for the glue, basically the cleaner/ straighter your cuts are the less likely you are to need a construction adhesive. PVA wood glue is OK, I use gorilla or ultimate glue because it will expand to fill gaps and it can cure QUICK if you wipe the joints with a wet sponge before you apply the glue.
