I have two different boards with different FPGAs (but pin-pin compatible). I know that I need two different quartus projects, but do I also need two different nios ii projects? The only thing different about the two boards is the size of the FPGA.

You don't need two different Quartus projects if you don't want to - you can create a Tcl script that sets up the project, and just select the FPGA/target.
You don't need different SOPC projects either. When you save an SOPC Project it does save the part number as part of the project, however, Quartus doesn't really do anything with it. In this project I wrote on the AlteraWiki:
http://www.alterawiki.com/wiki/using_the_usb-blaster_as_an_sopc/qsys_avalon-mm_master_tutorial I used a common SOPC builder file for the different hardware targets.
