Ahhh, the "Tetanus Express"
The freeze plug issue should be carefully looked at while you're there, but as long as the surface it sits in is OK, then I'd install a new one (all of them really) and see what happens. Were it me with that and the busted valve cover, I'd be inclined to pull the pan and head and have a look, then reseal everything anyway.
Can't comment on the lift points though, as I can't recall the layout of the 230 and its various mount points.
