You dont need a gfx card. What you have to do is use only IFF images, do not use JPEG ever on an AGA as backdrops, because they contain 16million colors and your workbench remaps the image to whatever colors it chooses....so it may look bad at one time, and ok at another.......use ONLY IFF...........if you want a smallr file but slightly slower, use GIF as they are 256 color images and very close to IFF AGA.
You can make your workbench look exactly like the link you gave, except the screen will be 640 x 400 (recommended best over all most functional Amiga resolution for NTSC....650 x 512 if PAL)
All you have to do is get all those icons from the guy, and maybe the themes and convert everything to IFF and .info files.............what you do fist is take th image on that link..........and save it...........then load it just as it is into a WB background.................make sure your WB is in 128 colors or 256...............now load Personal Paint............then Grab your WB screen. save the palette. grab the HD icons as brushes if possible, and make anothr version of it right below but with a glow around it (outline it with white, then bright yellow, then slightly darker yellow) this will be the image of the icon when clicked..............save that HD brush with the glow version right below it perfectly alligned............save it as a .info/Icon with "both" set on PPaint save window.
save it into RAM actually, that way you can view it and click it to test it. now simply do that to each icon you like......using that same palette you saved...........once your done, your workbench will look cool and work smooth, the colors will look slightly dithered but trust me, it will look cool and you will have what appear to be PNG icons on your AGA machine with no gfx card.
:-) hope I gave enough details or at least got the ball rolling.
