How often do I need to replace mag springs in my USGI's?

Not very often.  30-round USGI mags are rated for a minimum of 6000 rounds, or 200 load-and-fire cycles.  They'll generally last far beyond that.  Most folks replace their springs long before it's needed, actually.  If you have GFs, and your mag stops working your bolt stop (but other mags trip it fine), then you might consider spring replacement.
