have it pro set up, it will cost about £70, but it will play much better and you will actually want to play the guitar, if it has a niggling problem then you wont want to play it, never heard of a piece of paper under the string at the nut end, and i would doubt it would make enough difference if the string is touching the fret as the vibrations of the string effected would still buzz against it when they are played let alone making a chord. The truss road would need adjusting and the bridge adjusting but if you dont know what you are doing you will screw the intonation up, so it will be possible to tune the guitar normally but at the 12th fret it will be out of tune - therefore making it impossible to play in perfect tune. If you have the necessary allen keys and feeler gauges then the set up info is available on the guitar manufacturers websites, but i stress take it to a pro unless you are confident, and when adjusting the truss rod do it a qtr turn at a time.
