Sorry, no answer from me, but I would like to know the answer to this question as well.
Yes, The receiver pins are the same as the Remington 870, so any stock that will fit the 870 will fit the 7400
No, the Remington Model 1100 stock has a hole (recepticle) through the inside of the stock in the pistol grip area to accept the action spring tube. The Remington Model 870 stock has no need for this hole so the 870 stock will not fit on the Model 1100 action.
No, Winchester 1400
