so what i'm reading so far is SP that grant multiple powers can be used together even when typically they wouldn't. So Iron man SP that gives him perplex AND outwit he can use both at the same time otherwise it'd say perplex OR outwit right?

correct, he can use both.

Related Question. If Ironman uses his outwit to outwit an opposing figures say impervious, then hits the character off of impervious can he then use super senses since he doesn't have anything outwitted?

I'm assuming he can't since he did use outwit, but I'm hoping that I'm wrong!

but the EE and PB can't be used together even if the SP grants both with the AND in between

correct. ee and PB cannot be used together.

You are correct. The Outwit is continuous until the beginning of your next turn. So if the character who was outwitted heals back to his Impervious clicks or regains Impervious then it is still outwitted...

The reason you cant use both is that EE and PB both require a ranged combat action to perform. However outwit, perplex, leadership, prob, are all free actions.
