Ahmet - my comments below. 1). Rust - I had an extensive review and survey of a 35mki before buying my 33ii. The rusty washers could well have been original, (as on the 35). would replace these with stainless, (make a plate if you can) large as will fit, and give it a surface to bear on. 2). Unsupported/repair under keelbolt. Yep, something happened at some point or the steel washer disappeared. If it were me, I'd remove the nut, do what I could to improve the bearing surface, add a washer or plate, re torque. 3). Belt of mat across this bilge. In the 35 I looked at there were traverse bands of unidirectional glass spanning (descending into, then out of) the keel stub. These were maybe 4"-6" wide, 3/8 thick if memory serves. I noticed them immediately, as they seemed unusual. Apparently not though, this was early '70s hot-rod fibreglass sorcery from the factory. Not sure if that is what you have, but it looks similar. In any case I'd leave it.
I agree with your approach. If it were me I'd address each keelbolt, one at a time, per above, while in the water. (Keel is firmly attached apparently.) I don't know that I'd use 5200, it will make.eventual fairing of the bilge more difficult. I think fairing the bilge would be nice but obviously much easier with the keel bolts out of the way.
