Min/Max Boards

Hello guys! I'd just like to tap the collective awesomeness of the BG minmaxer hivemind and ask for advice.

I've created a gestalt level 15 warblade/Eternal blade | Wizard (Focused Conjurer)/Incantatrix. The primary gist of the build is centered around two-weapon fighting via a homebrew discipline coupled with power attack and persistent wraithstrike, along with the occasional Quickened Repeating True Strike and a full attack with power attack for 20 the next round.

My feat selection is as follows:


Custom Vow of Poverty, homebrewed
Netherworld Gardener, to qualify for oslecamo's awesome Ancient Temple discipline.
Spell Mastery(Wraithstrike, Haste, Mass Snake's Swiftness, Greater Magic Weapon, Greater Dispel Magic)
Uncanny Foresight
Extend Spell
Iron Will
Persistent Spell
Homebrewed Two-Weapon Fighting
Weapon Focus (Longsword)
Power Attack
Improved Initiative
Quicken Spell
Easy Metamagic (Quicken Spell)|
Easy Metamagic (Persistent Spell)
Signature Spell (Wraithstrike)
Repeat Spell
Easy Metamagic (Repeat Spell)
Weapon Finesse

Now, I'd like to ask for advice on
a) which spells to take for my character
b) maneuver selection
c) tactics for dealing with out-of-combat necessities.

Thanks, all!
