i would also like the user to be presented with a list of all the

to accomplish this. does such functionality exist in the API?
The mapObj's getNumSymbols() and getSymbolObjectById() methods should
allow you to do something like this (untested):
$numsymbols = $map->getNumSymbols();
# Start looping at 1 since symbol 0 is the default symbol
for ($id=1; $id < $numsymbols; $id++)
{
$symbol = $map->getSymbolObjectById($id);
# Do something with $symbol here... see the symbolObj class docs...
}
