There have been many recent build request for Savants, and a scan of the forums should net you all you need to know as far as these (all very similar) builds are concerned. They are very simple. Spell selection is the real key to a Savant build.
These are my personal gear goals on my first life Lawful Good Drow Air Savant:

Triple Positive GS Cloak: +150 SP, +6 Ex. CHA Skills, True Res clickie, Cleansed

Epic Ring of Spell Storing (luxury item)

Pale Lavender Ioun Stone (more luxury)
Boots of Anchoring
+3 CHA Tome

Upgraded Regalia of the Phoenix, Red Dragonscale Robe, or Epic Robe of Fire. Helm of the Red Dragon (Fire Savant)
Epic Diabolist's Robe (Earth Savant)

Epic Ring of Elemental Essence

Litany of the Dead (non-Good)
Epic Dragon's Eye

Epic Cloak of the Zephyr (Air Savant)
Epic Dusk Heart
Epic Staff of Arcane Power
Epic Torc of Prince Rayium-de II
My decisions were based off my desire to cover all the major bases, while requiring little to no swapping, and having no redundant abilities. I accepted the fact that my Acid and Insta-kill were never going to be strong, and ignored Spell Penetration entirely. I do not want to TR this character, as the Feat selection becomes too tight. I also did not want to force myself into always needing to run epics to improve my gear, and much of the gear I was able to start working on well before I hit 20. If I do not feel up for a massive challenge or consumables investment, I have many laid-back options (Litany, Shroud, VoD, SoS, Crafting). I did not participate in the Crystal Cove, Mabar, or Risia events for various reasons.
Feel free to comment on my intended setup, but I put a lot of thought into it, and am pretty sure this will be my final loadout until better stuff shows up.
