1998 is when the K11 got its 3rd facelift with the big headlights and different shaped dash yeh? If so your answer is no, super s/SR tacho clusters won't fit at all. www.micra.org.uk will have more members with knowledge of your particular K11 series.
As for the brakes though, YES! the fronts will fit. The guys and girls at the Micra Sports Club will be able to point you in the right direction in regards to this matter as well. Alternatively, if you go to this webpage's main page and do a search for N14 1.6 brakes you will find plenty of threads talking about the modification.
