Well, where to begin...
1. You want timer Number 2-4499. There were actually three different timers made by two different manufacturers used during the production years of the machines you have. They were originally known as 2-4499-1 (Mallory design 1), 2-4499-2 (Kingston) & 2-4499-3 (Mallory design 2). I'll post pictures below.
2. Go to Home Depot, Lowe's or another hardware store and get an 18" 15 watt fluorescent bulb (can be either a T8 1" around or a T12 1.5" inches around) and a new 14-20 watt preheat fluorescent starter. Total cost will be between $5-10.
3. That's the time-delay bleach dispenser.
4. I would leave that rust be, myself. Others may have better suggestions.
5. Again, you could have that done. How bad is the cabinet and how essential is it that it be near-perfect? Remember that the top piece and lid are porcelain enamel.
6. Transmission work on these, while not all that difficult in and of itself, is often not necessary until there is a problem. That said, go and read this thread to see what is all involved:

7. I assume you are talking about the speed selector switch as opposed to the water temp switch? There is no way to open those switches up. You could try spraying some electrical contact cleaner in and see what happens. Those switches are not hard to find NOS (new old stock). Part number is 2-4498.
