Which enabler do you have in the System Folder? As I understand it the LC III + needs the 003 v 1.1 System enabler to work with System 7.x. You shouldn't be removing this from the System folder.
I'd leave out the RAM Simm for the moment and continue working with the 4Mb of onboard RAM.
I would agree with your guess on the bus error, as bus errors are normally memory addressing errors, but not exclusively.
Do you know with certainty which Sonnet Presto card you have?
