Bristol are great, you will not regret chosing them.
Equipment wise, a protractor (square one) if you haven't already and a good sientific calc, i have a casio fx-83ms, pens, pencils, a felt tip (for the wind side or the crp-5) ruler and anything else you can think of.
For the two of you going for mod one well you will find it bloody hard work but enjoyable, Alex, Bas, Tom and Ken really make the subjects come alive. I will be down in Nov for mod 2 brush up and cannot wait.
Enjoy
