how can I tell if berings are still good?

In case anyone is interested, that instruction sheet is here:

I install them exactly as you and the instruction sheet describe. The castle nut is hand tight only after tightening it down first to seat the bearings.

I think the "side to side play" you refer to is described at the very end of that document. The TM bearings are right at 35mm and below, so that means the amount of play you should detect with a 27" diameter tire (as with a 205/75R15), according to that document, is 0.08", which is a little more than 1/16". I guess that would be detectable if you were really looking for it. Good to know.
