Help 97 jetta gl

I just bought a Jetta gl 4 days ago as my first car it has 96258 miles atm and I am alrdy having some anoyying problems nothing major the passengers side molding is starting to come off the wires and stuff right about the pedals all fell out the key hole on the passengers side comes out with the key if i try to unlock it and finally the lock on the back door comes off the little plastic peice u pull up and down does anyone have any idea how to fix these things if so please post thanks.

I whould just use crazy glue to fix the molding problem that is what I used. I have a 96 jetta the molding sucks it always falls off.
