that is quite a good guide.
I wrote a set up guide for myself some years ago, that roughly contains these steps:
1. os3.9 + bb's (consider dual boot for os4.x while at it)
2. cybergraphx (I think 4.3 rc5 is latest, not sure)
3. set up graphics card and its resolutions
4. warpup (5.1, IIRC)
5. bppcfix or blizkick (you need a reboot anyway for OS3.9, so you might aswell use blizkick)
6. ppclibemu
7. warp3d (4.2 IIRC)
8. cybergl, stormmesa
9. set up right env vars and options for warpos, monitor driver and cgx
10. ordinary workbench enhancing stuff like MUI, diropus, reqtools, un/archivers, browsers, rtgmaster, xpkmaster, ixemul, kingcon, scout, swazinfo, visualprefs, ghosty, mcp etc.
hope this helps.
