well...i cant say i have looked up how to do it before i think i just kinda grew up with it, but as for bearings and such get as much grease in as it will take and gust gently tap them in(star pattern) with a fat screwdriver if you dont have a press. and the brakes on my "75" front end i do have issues with the calipers locking up every couple of years and laying waste to my bearings so your not alone there.
i think if you just give yourself some time (and another vehicle while the truck is down) you will be able to figure it out just fine.
Dont Wrench down on that castle not and remember to replace the cotter pin
