There isn't really a right or wrong way to tell, its really all about feel. With alot of Jap cars, they run large double row ball bearings, which I have seen completely fail but still very quiet. The bearings should spin freely, with a slight resistance (sealed bearings only) Wheel bearings are generally rated at about 15000 rpm (more for smaller ones) so sustained usage shouldn't be a problem. As far as using the right grease goes- its just there for heat transfer, the anti friction part is the actual bearing. Not to say you dont need it, but most sealed bearings come with a high temp synthetic grease from the packet... bearing seals should not be removed!!!!
Bearings generally fail from lack of grease- confused? Like I said, grease is mainly used as heat transfer, therefore lack of grease will make the bearing race heat up too quickly and failier isn't far behind.
As far as shock loads go, radial loads are the ones you got to look out for- ie drifting into a kerb- anything which thrusts the bearing race toward the center or away of the car.
As fas as upgrade- sure, there are upgrades, ball bearings- cylindricial rollers- angular contact. But what you have to remember is that the bigger point of contact of the balls/rollers, the limited amount of speed you can use. But you can get around that by using C3 clearence/single contact seals/brass cage bla bla bla
