Yes both cranks are moving together, so when you move one the opposite moves as well.

Use a press, not a hammer, to set the cotters, and be sure you have them oriented so the crank arms are opposite each other.
The cotters are solid. It's the main shaft I think that is loose.

Yes I have had to use that as a stop gap until I source some decent amber walled tyres over here in the UK. I bought two off ebay and the grip rubber was so soft the rear tyre has gone bald in less than a year. Luckily I had the original I took off (Raleigh Record) so I have had to put that back on again. If anyone knows where I can buy decent tyres please say!
I don't wear a helmet.
