Check the Tech section of my site - I've got a 1999FSM, so I've probably got the torque specs up there.
I usually only pull the pan every third or fourth time I change the fluid to check and clean the filter, since it's little more than a strainer anyhow. Do take the time to clean the magnet off (it's stuck into the pan.) Don't be worried about what you're cleaning off there now - just know that you cleaned it so you can see if anything has built up later. The particles and filings all over the thing this first time will be from transmission break-in, and some buildup there is perfectly normal.
I also find that putting in a few (three or four) studs, widly spaced, makes it easier to hold everyting in place while you get screws started. If you want to do so yourself, the screw holes are threaded M6-1.0, and you don't need very much stud (about 15-20m/m will do.)
I don't recall the torque spec offhand - what I've usually used is "two flats past finger tight" - turn the screws with your fingers until you can't go so (there should be no daylight between parts, but there's not a lot of tension,) and then an additional 1/3-turn with a wrench. Those cork gaskets are easy to crush...
