1) The package you point to is the arithmatic package, and it works just fine in Quartus (I used it many years ago successfully)

2) because fixed point arithmatic is just integer arithmatic, so no special IP is required

3) No Idea. make an enhancement request for it. The difficulty is in supporting the package generics that 2008 uses. But the '93 compatible versions you have downloaded work just fine.
