How much swap is needed is an easy calculation:
swap space = required memory space - physical memory
The tricky part is figuring out the value of "required memory space" :-)
on a machine with 4GB of RAM, for desktop use, you probably hardly
need any swap, but I'd give it 1GB just to have some.

If you were really using swap, you'd want it on a separate disk, as
fast as possible, and on a particular part of the disk to maximise
access speed. Real world, for your usage, it's hardly going to matter.
