Questions:
1. I would prefer to use screws (rather than nails) to add new
structural support, so I don't cause damage. 2.5", pre-drilled?

I'd do that.



3. One of the new 5.5" wide Trex boards will have to be "ripped" to
4.25". Is the stuff difficult to cut? Can I use a cheap 40 or 60 tooth
blade (do I need to use a router)? The Trex website suggests a 40-tooth
"carbide tipped" blade and/or router, I believe.


What do you mean by "cheap"? A steel blade with no carbide? No, I'd
not use that. Like any other product, the better the blade, the
better the cut but this is a deck, not heirloom furniture so most any
carbide blade will work.
