What I really need is the closest thing possible to a 2-port RAM.

So why not use a board with QDR II+ SRAM then?
The bottom-line is you have no hope of any sort of success without simulating your design. You need a simulation of how your camera interface works and how your VGA interface works. With those two simulations, you can determine if you can map them as Avalon-MM bridges, or if you can convert them to streaming interfaces. Then you can determined the memory interface requirements, so that you an determined whether you can use SDRAM or you require QDR II+ SRAM.
SDRAM is good for bursts, not as good for random accesses, but it can implement large memories and cheap. QDR II+ SRAM is good for random access, but its small and expensive.
