Which links did you change? From my experience the thrust arm is the one that always squeaks when old. It's the one that runs horizontally with the car and connect to the bottom of knuckle assy. If you replaced it already I would check tie rod. The tie rod has a ball joint that connects to knuckle assy. If it has excessive clearance change it. If not try adding grease to the boot. You should disconnect from knuckle to inspect for clearance and then add grease while moving it back and forth.
While your there check control arm bushings.
As for the trunk, if you locked the trunk with the key you most likely need to drill it. Try to contact a locksmith and ask for his opinion. However, I am pretty sure that he is going to tell you the same thing.
