These days I just keep the standard seal in, and forget about the updated version. The update makes no difference to the life of the seal. You can't tell whether you have the updated version without taking the flange out, so unless you can get both seals on sale-or-return just get the original since that works with either flange.
I always change the bearing as a matter of course because its cheap and has to come out to do the seal anyway. I see maybe 10% of them which don't need changing.
I don't change CV boots unless they actually need it. Worth noting you don't have to take the suspension apart to get the front shafts out. Take the inner CV heat shield off and with an assistant to hold the steering on full lock, you can move the inner joint forward slightly and then get the outer joint out of the hub past the brake caliper.
