A quick question - should I get the sleeve measured to see if it's still round, or is this a waste of time as it's very unlikely?

absolutely.....round rings in oval cylinder don't work so well

Saw that. Would I need to take in the piston, and the boring instructions as supplied with the 685 kit?

would not be a bad idea
