67,
Put the drum back on, leave the outer bearing out, then put the spindle nut back on (without washer). Grab hold of the drum and pull sharply towards you, this should pop the inner bearing and seal off onto the spindle.
The orange stuff probably means you got some moisture in with the grease. I would replace the bearings, races, and seals. Not very expensive for peace of mind.
Ball joints should not go bad within a year, even with bad boots. Enough grease should still be on them. Bad upper or lower ball joints can cause negative camber, however, the most likely cause is one of two things. You may have bad lower control arm inner bushings or the adjustment eccentrics moved.
