Just the one. You could have three, if there were a cruise control cable, and a kickdown cable for an automatic tranny, but you probably won't have but the one.
The OE spring should be plenty, but you can add another if you like, it won't hurt anything, it'll just make for a stiffer throttle pedal & possibly a numb right leg.
Check thoroughly for a vacuum leak. Any "un-metered" air between the throttle plate & cylinder head will raise your idle. The more significant the leak, the higher the uncontrollable idle will be.
