You might want to check out Fury Flechette's (elec/fire)/shield build collection here -> http://boards.cityofheroes.com/showthread.php?t=216944
(Warning : those are pre-inherent fitness builds, but easily tweaked)
Comparing your build to the "moderate" elec/shield build posted there, I'd say that one comes a lot cheaper than yours with the purples and has overall better attributes.
Also, I'm currently collecting the IOs for that moderate build (plus Grant Cover plus OwS plus Confront) and am therefore biased 
Your build : 63.8% global recharge, 210% regen, end delta of 1.83
FF moderate : 60% global recharge, 262% regen, end delta of 2.11
You will also have fewer hp because True Grit lacks the healing %
If you just want to tweak your build, I'd suggest swapping the slots in OwS and Tough.
After that, you might want to lose the -Knockback Steadfast and/or the BotZ -Knockback. Active Defense has enough -kb/-kd protection/resist.
Few recommendations below:
-Single slot One with Shield w/ Steadfast +3def
-Triple slot Tough w/ Aegis
-Six slot Stamina w/ Performance Shifter (adds 3.13% AoE def).
-Swap Kismet +6% acc in Combat Jump w/ LotG +7.5% rech in Phalanx Fighting. (Perma +6% acc and slightly higher def)
-Remove the -KB IO in SS and slot a Stealth IO
-Use a full set of Obliteration in Shield Charge
-Remove LotG def IO in Deflection
At the end of that, you will have 3 slots to play to improve on hit points, damage resist etc. Some people like to 2 or 3 slot Active Defense for the debuff resistance.

I had a look and it needed some adjusting, dropped char for fire blast so you have a functioning ST chain and gets some more recharge (you can swap ring of fire for Char but the hold set is just pretty expensive but you can take it if you want since it would be decently useful when purple'd), its perma hasten with the t4 spiritual but the endurance looks pretty nasty so I would probably go for cardiac unless your getting t4 ageless in which case the +recovery from it perma'd would probably mean your fine and definitely get the +end accolades.
The KB protections did nothing for you so got rid of them, then this has Perma double stacked AD with 88.9% DDR making you as high as it really goes unless you scrape a few percent more in battle agility but I tried to get you a few more recovery bonuses here and there since there was a fair few spare slots floating around
The FF Proc in Shield Charge does nothing either since it spawns a pseudo pet which steals your 100% Recharge bonus.
So here it is.
