'a short touch':

A 'touch' is any section of a method, beginning and ending in rounds, in which at least one bob or single is called. If no bobs or singles are called, then it is not a touch, but a plain course (not to be confused with 'plain hunting'). A 'short touch' implies that not many bobs or singles are called by the conductor, and hence the composition is fairly short, perhaps only a few minutes. In the context of NINE, then, 'short' does not refer to the peal which is rung, but presumably to the length of the introductory section -- hence the subtitle 'two courses'

'Kent Treble Bob Major':

'Major' means that it is a method rung on all 8 bells. Even if a tower has 8 bells and they are all rung, it is possible to ring a method on fewer than 8 bells, e.g. Triples is rung on 7 bells, and is typically rung wit the heaviest bell, the tenor, ringing last at the end of each change. In such a case, the tenor is not participating in the method, although it is recorded as taking part in a peal.

'Treble Bob':

In a treble bob method, the basis of the method is not 'plain hunting' but 'treble bobbing'. In a standard method, the treble always plain hunts (that is moves from 1st place to 2nd, then, 3rd, 4th, 5th, 6th, 7th, 8th, then back again, 8th, 7th, 6th, 5th, 4th, 3rd, 2nd, and back to 1st place, i.e. to the lead, and so on continuously). However, in a treble bob method, the treble bobs (or dodges) at every other stroke, so that it progress from 1st, 2nd and dodges back to 1st, then 2nd, 3rd, 4th and dodges back to 3rd, then 4th, 5th, 6th, and dodges back to 5th, then 6th, 7th, 8th and dodges back to 7th, then two blows at the back 8th, 8th, down to 7th, and dodges back to 8th, then 7th, 6th, 5th, and dodges back to 6th, then 5th, 4th, 3rd and dodges back to 4th, then 3rd, 2nd, 1st (lead) and dodges back to 2nd, then 1st (lead again) and repeat continuously. Got that? Phew. Meanwhile the other bells are doing their own work. This is also based on the same bobbing course, but somewhat modified so as to avoid the repetitive rows which would immediately result.

'Kent':

There are a number of variations on the Treble Bob theme, The two best well known are Oxford, and Kent. Oxford dates form 1677, and Kent from 1788.
