Dave,
Don't hesitate, grab the bloody saw!
You can make a an adjustable fence, just clamp it down on each end. You can make an adjustable miter gauge also, heck, you build models.
The blade guard, I tossed mine. If you really feel you need it, I'll see if I can dig mine up.
Hey! If for nothing else, the Dremel table saw is perfect for notching LE's and TE's.
Besides, with all that stuff missing, the guy should just give it to ya!
