I got a huge water report

I want to use the John Palmer worksheet but only have only managed to pick the following from the masses of superflous information :
Sulphate 25mg/l
Chloride 25mg/l
Sodium 12mg/l
Hardness 63mg/l as CaCO3
Alkalinity 25mg/l as CaCO3
I have no figures for the Calcium or Magnesium needed for the worksheet. Can I estimate these based on my other values or area? I have a value for Manganese, though I suspect this is totally different to Magnesium? As or the Calcium?
Also I typically brew pale and belgian ales, is my water in the right ball park for these? I am also intending on brewing another Fuller's ESB and Guiness clone this year, would my water need adjusting for any of these brews?

I have seen some advice that a teaspoon of Gypsum should always be added regardless but that seems a bit of a blunt tool?
Thanks in advance for any advice.
Dean.
