Min/Max Boards

Wow, thanks! These are great. I'm still working through each specific thing, but I appreciate all the detailed help.

So, my character was unceremoniously murdered by another PC (evil campaign). I need to make a new one, but all the other PC's are optimized to hell and back. I've read the handbooks (http://brilliantgameologists.com/boards/index.php?topic=10238) and multiple threads, but I still feel like it's missing something. Here's what I have in mind, but it would be nice to get some feedback!

Warforged Psion Shaper
Lv. 9 (starts there, will go higher)

Ability Scores
Str: 8
Dex: 16
Con: 12 (+2 racial)
Int: 22 (18+4 from items)
Wis: 10 (-2 racial)
Cha: 4 (-2 racial)

Feats: Psicrystal (Nimble), Overchannel, Adamantine Body, Personal Construct

Powers Known:
1: Vigor, Minor Creation, Inertial Armor, Entangling Ectoplasm, Astral Construct, Crystal Shard, Energy Ray
2: Share Pain, Control Sound, Psionic Repair Damage
3: Energy Wall, Time Hop, Touchsight, Telekinetic Force, Telekinetic Thrust
4: Psychic Reformation, Fabricate
5: Plane Shift, Anticipatory Strike

Items:
Animated Mithral Shield
Headband of Intellect +2
Arcanist's Gloves (Ruled to boost the PP I can spend as well as ML)
Scarlet/Blue Ioun Stone +2 int
Torc of Power Preservation (-1 PP Cost)

Main Conceits:
1. Overchannel+Arcanist's Gloves+Torc of Power Preservation gives ML+5 on augmenting damage powers like energy ray.
2. DM has ruled that I can "wear" my constructs around me like a second armor, allowing me to tank and getting extra actions in addition to the share pain+psicrystal+vigor combo (not that this saved me the first time around)
3. Anticipatory Strike fixes initiative issues at the cost of PP, and AC as a swift action means I won't get caught off guard.

Things I'm Considering:
1. 1-level dip into factotum for that +6 bonus to attack rolls and saves seems quite attractive, but I'm not sure if it's worth the ML loss.
2. 1-level dip into mindbender might be nice for telepathy.
3. Expanded Knowledge: Schism might be worth it, but I'm not 100% sure.

DM rulings are super loose, and other PCs are, like I said, absurdly powerful. Do you guys have any suggestions on how I can better optimize my character? Any source is ok, just let me know where things come from. Pre-emptive thanks for the help!
