it's pratty easy to do, and there aren't any small things you can break, unless you are really uncoordinated.
You have to remove the black panel surrounding the guages, so that means all of the wiper switchgear, and possibly the steering wheel so you can get the panel out from in between the dashboard. Try setting it onto the low adjustment pos first. you may also have to remove a few screws from the panel underneath the steering column as well, but i haven't taken mine apart for a while so i cant remember.
if you don't force anything, then you probably won't break it.
also, the nuts on the wipers are hard to get at with a socket, so try a shifting spanner or multigrips if you still can't loosen them off, do them up finger tight afterwards, so you can undo them easily in the future if need be.
