LOL OK fair enough. I am tailoring my response to OP and he has a GF1. It maxes out at 3200 but the results aren't pretty given such a (relatively) tiny sensor. 1600 is the most I'd ever use but I even try to avoid that if I can.
You have a couple of photos that are great... you must be very good at photoshop!
