Credit card still slides under the ninth fret but only just. I probably can't do much more with this?

Second problem:
The issue I mentioned above with the difficulty of doing open an open E Maj chord or bar chords near the nut is due to the string heights in the nut slot I believe. It's very difficult to hit the notes, I have to press very very hard. I have no issue on my other electric guitars. In step three of the "Setting up your Intonation" guide Gavin1393 mentions two methods of adjusting the nut.
I don't have a nut file but have some spare new strings to use as a file or the other method is take the nut off and sand the base of it.

Before I do anything irreversible, I would appreciate some advice on the best method to use?

Cheers,
Alkay.

That sounds like your 1st-Fret action is set too high, what you could try doing is sanding-down the bottom of the nut till the 1st-Fret action is low enough so that fretting chords is easy enough without the strings buzzing against the 1st-Fret.
