As Nic said it depends on what you use your car for but in terms of braking components the rule is the same as tyres and you shouldn't be looking at anything less than OEM. The EBC stuff doesn't seem to be very well rated and if you want a performance set up any of the traders on here should be able to help you.
I recently replaced the pads on mine with OEM parts and found it quite a straight forward job including the fluid bleed. If you're confident enough then you could save yourself a bit of money and be safe in the knowledge that you have done everything neeeded.
