Please can someone tell me how to work out what notes to play? I've seen a few in the past day or 2 (G/B is another) - I'd like to be able to work out what the chord notes are.

Look at the chord construction thread in one of the lessons forums. Basic chords are always made up of the 1, 3 and 5 notes of a scale.
In a G chord, the notes would be 1=G, 3= B and 5= D. In your example G/B, you can see that the third is to be played in the bass as a chord inversion. The most common slash chords put either the 3 or the 5 as the base note, both chord inversions.

Likewise, the C/B would indicate that you would play a C chord, but the bass note would be a B. In essence, this would be a Cmaj7 chord, if I'm not mistaken.

One way to play that chord would be:
---0----(E)
---1----(C)
---0----(G)
---2----(C)
---2----(B)
---x-----

Or

---x---
---5---(E)
---5---(C)
---5---(G)
---2---(B)
---x---

Chances are pretty good that one of those chords would work in the song you are working on. Hope that helped.

That works for the few oI tried, seems obvious now Thanks

I made a bit of an oops in my post above- the correct notes are as follows for the first example- I misnamed the note on the 4th string:
---0----(E)
---1----(C)
---0----(G)
---2----(E)
---2----(B)
---x-----
