Some things have to be dealt with, for example ampersands or underscores, which are special for LaTeX. But a formatting command like
textscto make small caps (most of your stuff is in uppercase, which is not only ugly and kinda formatting information, but also makes using textsc pretty pointless) will distract biber. Biber tries (quite good) to split the names in its parts, so you can decide how your names are printed in the document. For example, you can decide that the first author has the family name gien first and all other authors have the given name first. Well, acually that would be the default for most styles, so you probably would want something different.
