You can load graphics sound and your program anywhere. Personally I load
my graphics and sound to 0x80090000 to 0x800FFFFF and my program from
0x80100000. I find its best to put the graphics and sound before the
program as the program is bigger than it looks due to uninitialised data
(the gpu work area being the biggest problem), which can cause problems
with the graphics and sound being overwritten if they are placed after
the program.

Once your graphics and sound are loaded into memory they can be
transfered to graphics and sound memory freeing up that area, which can
then be used as you wish (this does mean that you'll have to reload the
graphics everytime you run, and maybe the sound unless you alter the
program so it only transfers from main memory to sound memory on the
first run each session).

You maybe wondering if you can load direct to sound and video memory.
The answer is no, not even full developers can do this, its to do with
the way the playstation is put together.
