Winter project carb rebuilds

So got some time to scrub. A bit more to go so in for another soak. Stuff is working ok. Ill go sttonger concentration for last soak.
Question, the choke shaft and/or housing is slightly worn. Should I remove and have it bushed?
See pic, linkage is bent and needs to be straightened.
Also, 2nd pic, can those steel pieces with the slots be removed? (Not sure what they're called)
Thanks
Steve
