You would still need a PCI core although you can get those a lot cheaper than PCIe cores. You can even get a free one from OpenCores (there is a PCI to wishbone bridge for example).
I don't think you need anything PCI with the specified PLX chip. The PEX8311 has a description of: "8/16/32-bit, 66MHz, Local Bus to PCI Express Bridge"
As far as I am aware there are no PCIe equivalents to the PLX 9054 (for example) - ie PCIe to local bus bridges.
I believe that is an equivalent, but still relatively expensive in comparison to just a PHY chip.
You might need some information about laying out your board for PCIe compliance however you can probably glean that information from a PLX example design :)
Very true - they seem to have the board layout all right there from their reference design development board. Pretty nice!
