The alternator has nothing to do with stalling. When did you last replace the fuel filter? If the engine light is on then have a repair shop scan it and repair it. It is cheaper than guessing.
No, auto parts stores show different part numbers.

probably a TH700, but take a look underneath
it could be a bad vacuum line or it could be the the throttle position switch
how do i get the key tu turn in a 1995 caprice classic, if it stuck? It could be the ignition control switch located on top of the steering column which will need to be replaced or the key cylinder itself.

None, there is no such thing as a 1998 Chevrolet Caprice Classic
Yes you can.
It is not possible to replace the trunk lock on a 1993 Caprice Classic while the trunk is closed. A person will have to remove the back seat, crawl into the trunk and open the lock manually before it can be replaced.
