You must use "stosb" (or if you're paranoid, "a32 stosb") rather than 
"stos byte [edi]".  Yasm (and NASM) do not support the latter syntax.

Most likely this is what's causing the "instruction expected after label" 
errors too; e.g.:
label: stos byte [edi]
Will generate this error, as stos isn't an instruction.
