There are two ways to go on the seals. There are very few seal applications for which you cannot find a modern seal. Folks like Kanters and Max have done the research as to sizing and seal materials; you can make life easy by paying them a bit extra for their research, or you can research it yourself. The best site I know of and one that I often use to find seals is the Timken website. You'll need to know the shaft diameter, the housing bore (seals are usually about 4 to 7 thousandths larger than the bore to allow for "crush" when installing), the seal thickness, and of course the type of seal lip and the material of lip or sealing surface construction. For gear oil, leather is far preferred over synthetics and rubbers. The Timken site covers all this in extreme detail.
Regarding the gasket between the pumpkin and the housing, you need to stay pretty close to the thickness of the original gasket; otherwise you'll be altering the alignment of the axles to the wheel bearings. Just measure the thickness of the original gasket and buy some gasket paper of the same or very similar thickness.
Though it may take a bit of effort and some creativity, rarely do you need an axle puller. No clips, axles are retained by the backing plate for most years (not sure which year/model you're speaking of). If you do change the wheel bearings or axles, don't forget to recheck the axle shaft end play and adjust as needed - very important.
PS - you'll have to rattle around a bit to find the specific information, but here's the starting point:
