Knick knacks? Do you mean, what you might be forgetting before you put it back together? Take anything apart that you can, and re-oil, regrease it. You'll end up making adjustments/repairs down the road, and a small investment in time now, as well as the learning experience will really help when you're hunched over the machine in a mid-February rainstorm looking for the right lateral pin where it hooks to the T-20. 
If you're sticking with the two stroke for now, how's the throttle cable? How's the ignition switch and the rest of the wiring look? Twisted and black-taped connections aren't your friend. Aside from little esoteric amphib crap that you might not be initiated to, look for obvious stuff that as a dude, you KNOW isn't right. Wobbly, wiggly worn parts, broken sprocket teeth, seriously rusted stuff that your pictures might not show, etc. Has the whole thing been degreased? Get a bottle of simple green/ purple power/ 222 (whatever!) and soak her down and hose her down. Every part.... it'll make life better. She looks pretty clean overall, though. These are insanely simple machines that just have odd quirks that usually manifest themselves in every different model. The frame/ axle bushings, etc. are known weak points in an older, heavily used Max II, and people seem to have addressed that. Plan on getting new axle pins (shoulder bolts) for the sprockets. I would triple check the play the sprockets have on the axles. Once they get loose, they'll work hard to wear the sprocket tube and the axle, until something, a pin, the tube or the axle eventually break. As a whole, people don't like to maintain these to the level that they should. I'm often guilty of it as well, but I'm trying to become more diligent as I go. Take things slowly, despite how excited you are about getting some stick time.
