Need some assistance with Rad/EM Blaster.

So I am looking to make this guy strictly PVE. Looking for good AOE Dmg, Single Target Dmg, and survivabilty for Trials/TF's. I can afford up to UC/Rare IOs. I am still learning everything so any help would be great.

I love my Rad/Em Blaster. Stun stacking, punching, heat vision - she's a regular supergirl.

Ive gone for Kinetic Combats, but on a budget I'd prioritise like this:

1) Slot Thunderstrike (6 pieces) in XRay Eyes, Cosmic Burst and Neutrino Bolt. Its cheap, gives you capped damage and 50-60% acc, rech and end redux in the powers, and will grant you 12% or so ranged defence, always on.

2) Crushing Impact, 5 pieces in each melee attack. This gives +Recharge, which means more Aim and Build Up, and similarly good values for you powers. ON a Blaster, I'd skip the Acc/Dam piece, you have Aim and Build Up, Rad's inherent accuracy and -Def, and global accuracy bonuses coming out of your ears by now.
Its cheap, but a bit more than Thunderstrike.

3) Positrons Blast, 5 pieces in Electron haze and Neutron Bomb. More recharge. This is getting a bit more expensive.

4) Eradication (4 pieces) + a cheap Dam/End in Eradication. More energy/Ranged defence. Maybe do the same for Atomic Blast after.

This will also give you +10% recovery and some extra end, and your powers will be cheaper to use, so 1 slot in Conserve Power may be OK.

Sorry, thats for Irradiate.
