Moisés,

Probably none of these will cause a problem. For the most part a SP fixes bugs in the runtime library (SP3 being an exception). It's best for the client to do a new install if you send him a new executable, but probably not absolutely necessary. The client simply won't get the "improvements" connected with the SP.
