The feed dogs look like they have old dust gathered down there, but I'm sure you will get around to it. It took me a few attempts too, to get all parts up to par (Actually a week). The black japanning shines up wonderfully with car polish :-)
Thread snapping happens if you have too small needle eye for the thread used. If you use heavier thread, max out on needle size like #18 or #19. The old cast iron models can use up to size #22, and they can have an advantage some times (I found them on ebay).
