I would get a datasheet for those memory chips. That will give you a pinout -- which pins have which functions. Then get out the multimeter and trace out which pins those resistors connect to and what they connect them to. Are they doing something simple like pulling up/down chip enable? If so, you'll need to install the two unpopulated resistors probably. Or are they doing something more or less complicated?
The unpopulated capacitors are almost certainly straightforward. They're just there as voltage smoothing ("bypass") and when you install the next two chips, install the corresponding capacitors to smooth the voltage for those chips.
