Yes..you should use the grease in all the places mentioned by WD40 and why would you want to bend the shifter?
If it was to have a bend it would've came with one ;) Just cause the stock one has a bend in it doesn't mean that the aftermarket ones should.
Beginners can drive fast in a straight line...
Intermediate drivers can master corners...
But truly advanced drivers find their own course and that's how they get ahead.
