285134 is the correct kit for the seals. It covers older and newer machines so there will be some parts you won't use. I wouldn't replace the bearings unless yours are badly worn, that requires a special tool.
383928 / 285896 I believe is the short post spin tube. Will likely need to find that on eBay as it is probably NLA. And for that matter, compare the price of a whole new basket drive which will include a new spin tube vs the spin tube by itself.
Agitator shaft will likely be more difficult to find.
I would also get a new agitator spring/seal kit 285672 since you are opening up the transmission anyway. They aren't usually that expensive and your spring may be rusty by now and the spring can sometimes break anyway.
But, if it were me I would still pull out the basket and inspect the outer tub real good before you start ordering parts. If its salvageable you might want to replace a couple other things too depending on their condition when you take a look.
Good luck and let us know how it goes
