Can the foam be cut down to a smaller size? (Without the outer cover on, of course)

Yes. If you use a utility knife with a blade for the sharp edge, it is very easy to cut the foam.

Will the Twin xl fit on top of my couch bed size 49x75?

The only way to find that out is to measure the couch and the mattress topper it sounds like you would need a full size topper

Is the cover waterproof?

I wouldn't think so since it is washable..

I have an overly plush mattress. Will this work?Or is it made to top hard mattresses?

I would say it should. I used it on a soft mattress and it was very comfortable.
