but my original triggering problem still exists: when i use the master_write_from_file in system console, that seems to jam up the following nios code:

Sorry, I can't help you with that. I have used SystemConsole and SignalTap II for triggering, and for the longest time they did not work well together, i.e., you had to make sure you opened the JTAG master server before clicking on the trigger in SignalTap II.
Given that you are trying to access NIOS II debug channels over JTAG as well, I think you're just asking too much. Think about what you are trying to do, and try another method.
For example, what board are you testing with? A simple solution for many boards is to use a USB-to-UART cable, eg., the FTDI FT232H cable and use a proper UART over that channel. That way you can see the output from your NIOS processor, yet it will not interfere with SignalTap II or SystemConsole.
