Thread lock acts as a lubricant while assembling, it also provides anti-corrosion protection when cured. Grease will simply stop it working as designed. For most parts on a bike it should not however be necessary [IMHO]- if the parts are properly prepared and assembled, you should not need threadlock and it can make dis-assembly a nightmare in some cases. I've had the joy of removing 3-piece BBs that have been threadlocked and it ain't fun. The exception is Campagnolo outboard bearing cups (used on later 10spd and 11spd cranks). Here Campagnolo virtually insist you use it (and a specific grade too), BUT you are not supposed to spanner up the cups, just hand tight. It allows correct alignment of the two cups during curing of the threadlock. If your Italian RH BB cup or bearing is working loose, then either the BB threads were not prepped properly or you didn't do it up tight enough or both.
Threadlock IS handy for any odd small nuts and screws where you can't get a locknut on or don't have one handy, and for extra safety on brake calliper retaining nuts etc.
