What programs are you after? The Amiga.org collective membership can probably tell you where to find them. :-)
As for SASG's stuff, I don't see any reason why it shouldn't work on AmigaForever. Nearly anything should be able to work with the right configuration adjustments.
Icons are all just a matter of preference. A default AF install probably uses 3.9's GlowIcons. SASG favors MagicWB, which will look off in a default Workbench color palette. 3.9's Workbench Preferences offer an easy way to correct this. Actual AF6 owners can correct me if I'm wrong ;-)
