1. most of the time places to install them are in listed in the ReadMe file ((yeah you should actually read them if u don't))
2. I had the same prob with the banscene patch, to fix it, i just reinstalled it because I bought it ((it was only $4..99 and it came with another game too))
3. I don' t really think there is an program that makes installin stuff like that available.
Just watch out for some things though. There is a car and a track limit. I can't remember what it is.
there are several programs you should get to go with it tho IMO. GTVE and Track Manager if you just play. If you plan on editing any cars ((painting, modelin, ect)) you also need MASpuce to take apart the mas files.
there are lots and lots of sites out there about it, but a lot are dying now because the game is older. it's still a great game though! I have a pretty large list of sites if you want some links. the best one is
www.speedsims.com but it is down ATM because they are moving to a new server.
also, if you want some cars from Need for Speed 4 converted to SCGT, i would be happy to do so for you if you would tell me where the car is located for download.
