No answers yet so I'll try to comment although I'm still a novice myself and there are so many ways to go with PB slotting. I have to say I've been very happy with mine though so I can't have gone entirely wrong.
You say you're planning to spend most of your time in human form, and it makes sense too because you've taken and slotted well all the shields. Retoggling can be a pain so your playstyle will probably be very different from mine. You will not be changing your forms as often. (I tend to change several times in a fight). So with that in mind, your human form attacks look underslotted to me and you have very few of them (Dawn Strike and Photon Seekers don't count because they're very situational with their long recharges). You don't want to be standing around in your fancy shields, doing nothing, waiting for Incandescent Strike to recharge.
I would slot all the human form attacks you have up with 1acc, 3 damage and 1 or 2 recharges. Perhaps even consider taking Hasten or another blast. I would take the slots from Dwarf attacks. Dawn Strike could probably do without acc too as you always use it with Build Up anyway. And IIRC if you use the shields with light form it takes you up to resistance cap so you don't need to slot light form for damres at all if you have the shields. Memory might be hazy there though, I don't have the shields myself. If you're still short on slots after all this, I'd rather underslot the non S/L shields than attacks. You're not a tank, you're a more like a slightly more sturdy blapper, so you need to eliminate them before they mez you, detoggle you and kill you.
I prefer slotting Essence Boost with recharges btw, although I'm planning to add heals too as soon as I can spare slots.
Heard you'd gone for a PB False. 
Quite agree, human attacks are a little light on slots. Mine are slotted 1 acc, 3 dmg, 1 end rec, 1 recharge. With hasten running I can dish out some respectable damage in human form (when not asleep/stunned/on my backside). I prefer recharge and some heal in Essence Boost and Reform Essence as I think it's better to have them up when needed than be waiting for a big heal. Personal preference tho. Drop the to hit buffs from Nova, they don't help much - less than an SO if I remember rightly. Better slotting the Nova AoE attacks with acc, don't want them to miss.
Agree that running your shields when in Lightform gives more than enough resistance so might want to change those damage res to recharge - it takes an age to recharge and you don't want to be without it when you need it.
Meh, i spend all my time playing ze squid :S hes so cool
Hio guys. Would u mind of giving me some suggestions about powers selection and respective slotting? I'm planning a Tri-Form PB. I'll probably play as Human most of the time, but I'm trying to take the best of Nova (slotting the AoEs) and Dwarf (to tank a little if needed) aswell. Here are the powers that I would take (don't look at the order pls.. I'll probably change it :P ). Cheereos
