I had springs fitted recently and had a full wheel alignment from a reputable tuner. This was necessary they said (plus the clutch was fitted too so I'm pretty sure the front sub frame was loosened) but the set up is great and I have had no problems at all.
I'd say always get a professional outfit to do the work rather than a backstreet abortionist garage who may have had very little experience in properly 'setting up cars' as opposed to just 'changing bits' over.
