To use VGA out, you need a flickerfixer like DCE SCANDO FF. To use a NIC card with TCP/IP you need at least 4 MB of RAM. The only solution to have a graphics card is buying an BlizzardPPC and a BVision. A 060 is very fast with Workbench operations.
Do not forget to buy a CD-ROM for your Amiga, because you can run AmigaOS 3.5 or 3.9. In these OSes, there are tools you need for TCP/IP, AHI and Graphics card.
