You could have the sketch look for a specifically named csv file on your SD card and, if it finds it, get your firing commands by reading the file. If the file is missing, have it read from the serial port instead.Alternatively (and perhaps a little safer) add a switch that you use to tell the arduino which option to use.
Is there anyway you can look at the above file and maybe give me some pointers on at least some of what needs to change? or point me to the right tutorials I tried searching the playground and googled it but really didn't find what I was looking for(or maybe did not fully understand what it was I needed to do) So I can start playing with it, I am still really green at this, but with some guidance I think I can handle it, or at least get close. Also I know you can power the UNO board through the power plug, would a memory stick (USB drive)work for this better than a shield on the UNO board itself?
