Hi, yes I fitted Excel-Gs all round to my Brava a few years ago, they are good value and feel slightly firm or sporty (at least when you first fit them you notice). I'm happy with them, although I like trawling ebay to see if there are any bargain Sachs or Boge units as they are very good too. The "ordinary" Bravas, Bravos and Mareas all seem to take the same shocks unless they are diesels or 2 litre jobs.
I'm not sure if or why you are changing the springs and if KYB or Monroe do them, but if you get a reasonable make of standard height you should be fine. Obviously a lot of people are changing front springs these days because of speed bump damage, so there's plenty of choice...
