Seems pretty easy, once leveled all all, I have only one stud behind
each of the two new base cabinets.

So, in the back of each cabinet one 2.5-inch pan head screw into stud.

Also to hold the two cabinets together, three deck screws, two along
the top and one at the bottom front are holding these cabinets
together...enough??

Plenty

Wouldn't be a bad idea to shim any gaps at the floor.
