I don't stir the compost as if I'm making Christmas Pud I just dig in with the compost stirrer tool and lift everything a bit and let it drop back, just to get air in there. I can be a bit more vigorous with the smaller 2 bins, but if I'm not careful I could vanish head first into the larger one
I quite like those ghostly potatoes growing in the compost, Dove is right; a bit of movement with stirrer or fork and they soon stop growing.
As to the bigger/the hotter, it would depend on what is in the heap, but it is certainly true that those very tiny bins can't hold the heat well. The relatively new Hot Bin (£150) is about the size of a wheely bin, has walls about 30mm thick, uses some kind of wood pellets in small quantities to help the process and reaches astonishing temperatures in 24 hours. You have to fill it all at once to get that going.
As to wood chips, use caution, not too much at once. Perhaps a little sprinkle now and then.
