Help With Changing Spark Plugs 96 GrandAm SE

I just need someone that could break down step by step how to change my spark plugs. I know where they are but i've heard you had to losen the motor mounts to get the the back 3. Just wondering if this is true or if there is a way around it... plus I don't understand the whole "gap" thing... so that would be very helpfull as well... Thanks.
