Start by taking off the trim using a small pry bar and hammer. Be careful because old wood tends to be brittle and you may want to reuse the trim.
Tip: The best way to remove the nails from the trim is to pull them through the back using pliers. This will preserve the face of the wood.
Use a Japanese pull saw to cut each side of the windowsill. Make a cut on each side and one in the middle.
Once the windowsill is cut, pry out the pieces using a small pry bar and hammer. Split the wood with a chisel and hammer if necessary.
Note: The support pieces from the upper cabinet rest on the countertop and will need to be modified. The new countertop is thicker so an extra 1/2" clearance is needed.
Cut two pieces of 1/2" stock (small) to put on each side of the support. Nail into place using the impulse finish nailer and 1" nails.
Lay the blade of the pull saw on top of the stock pieces and cut through to the back. This will ensure an extra 1/2" of clearance and a nice clean edge. Knock the pieces out using a pry bar and a hammer.
Use a drill with a spade bit and drill a starter hole in the countertop. Pick an area that has no supports or obstructions under it and drill the hole.
Using a reciprocating saw cut through the countertop from this starter hole to the front and to the back. Do this in a couple of places.
