On a 3560, configuration features, that are not supported in the downgraded IOS, just don't function, or, I believe I recall, appear in the running config. If you not using any of those features, you won't notice a functional difference.
BTW, I also recall the original 3560/3750 switches had lifetime software and hardware warranties, although I also think I recall, Cisco later changed that. If you're the original purchaser of the 3560, you might check with Cisco and ask about lifetime software support. Otherwise, as Philip mentioned, if you cannot download the IP Services image, that normally implies you cannot download an IPBase version either.
