The wagon seems to be now losing transmission fluid significantly worse since it wasn't running for a month...I know the front seal is leaking. I'm leaving relatively large puddles everywhere I go now.

1) Does this require the whole tranny to be pulled?
If so, should I look into doing any sort of rebuild since its out? I'm currently at 94k miles. I've heard some go at ~160k and others can do 300k+.

2) Would it be possible to swap the fluid to a high mileage fluid with additives to swell, or think that will be just futile?
