this hand got me. i hate it when this happens because i feel like he's just shoving because i showed weakness on the turn. i know there are diamonds and an A but he could easily limp/call preflop with 99,88,77,66,55,44,33,22 and it's unlikely he hits a set. he could have a set but i think he would have bet turn with it? what do you think?
equilab says im 70% against his range according to his VPIP & PFR... but it's not a nice sample... also, i don't understand how i can say im 70% here given his play... surely we need to adjust since his range will be even thinner when he is betting like this?
You are very likely beat. 
What kind of range are we talking about? Put that into equilab and paste here.
