This is copied from the OEM manual but unfortunately I don't know how to copy sections from a .pdf file and post them. Hopefully you'll find the torque values you need but if not, PM me and I'll try and find them. I can't recall if I did the belt replacement exactly the same way as you, I think I removed the power steering/coolant pump pulley at one point but it's been a while.

I can't recall why, but for some reason I wasn't able to remove the PS pump after pulling the bolts so I reviewed the PS pump removal procedure which detailed removing the two small bolts shown in the image below. That allowed me to get enough room to slide the old belt out and the new one in.
