If you have Android 4.0 or higher, you can disable stock apps by going to Settings/Apps/All, selecting the app in question, and tapping Disable. This doesn't remove it from the system, but prevents it from activating (so it still takes up app storage space, but won't occupy any RAM). There are certain stock apps that you just can't disable--the button will be greyed out for those.
If you want to completely remove stock apps, you'd have to root the phone, but if you're a novice, I wouldn't recommend it. You could seriously mess up your phone if you don't know what you're doing.
