I'll add to the chorus: Core is Core; DMG, MM1, PHB.
For my "de facto" core, I'd add Unearthed Arcana (only approved variants, though), the additional bestiaries (MM2, MM3, MM4, FF), and the Magic Item Compendium. I haven't reviewed Spell Compendium enough to know, but I think a lot of the spells therein may not be considered "de facto" core for my purposes.
My preference, though, is SRD, minus psionics. I've played with psionics, and they did not improve my game any, while adding some headaches, so I don't want them in my games. They're good, but they just don't work for me. YMMV.
Hope that helps,
Flynn
