1. I used new 1/4-20 stainless "T" nuts for all of my pedestal bases. Be sure to install your pedestal bases on the decking after you install the new carpet but
before you install the decking back on the boat to make sure the end of the 1/4-20 screw is flush with the bottom of the plywood. the pedestal bases sit over top of the aluminum deck framing below and if your screw isn't flush with the bottom of the decking and it hits the framing and it will hold the decking up from laying flush on the framing.
2. Removing the horizontal decking is easy and makes for a much better job when you wrap the carpet around the edges an onto the back of the decking. Re-attaching the pedestals with wood screws won't be as secure at the "T" nuts, and if you don't re-tighten them every season (3 months) they will loosen and strip.
Another
HUGE plus to removing the decking for carpeting is being able to re-install the newly carpeted panels with exposed fasteners through the new carpet. This makes for easy decking removal without having to rip up your nice new carpet job to get to the fasteners in case you have to make below deck repairs like livewell leaks or hull breaches... or if you just want to make some kind of below deck modifications or inspections.
3. Hatch covers are an easy removal too, just drill out the rivets that hold them to the hinges. You'll need to do this to wrap the carpet around the edges for a snug fit when re-installed. I used 1/2" 8-32 stainless oval head machine screws and nyloc nuts to re-attach them for a more secure installation than the factory open end pop rivets.
If you plan to reuse your old decking, removing it from the boat will make removing the old carpet adhesive a lot easier. I used a belt sander with a 30 grit belt for this, it worked well.
After removing the old adhesive you'll want to seal your decking, epoxy resin is the best for this but exterior grade spar urethane will also work... 3 or 4 coats of either. This is what my old decking looked like before adhesive removal and after sealing:
4 coats of epoxy resin.
... and here's the hatches removed:
