No, they simply are more instructions for you to use. You *do* have to
add some logic for fallback routines though. This usually comes in the
form of a function pointer. 3Dnow! and SSE are even more interesting
(MMX does only integer, 3Dnow! and SSE can do FP).

do not know if each individual "items" (players, monsters and so on) are
drawn with multiple 3D polygons or are used in a "sprite" kind of way.
I am not sure from memory, but I actually think that BG2 will *require*
a 3D video card, much like Q3A (i.e. there is no software renderer)!
