I think those splash baffles just pull out. Make sure you put them back the same way.
If the shaft is bent and worn It may be worth pulling to straighten and bushing if you feel like. I kinda' lean if it works don't fix it so. if the shaft is true, for the bent part, I think I'd just try covering some log nose pliers with thin cardboard to make a "soft jaw" and try to straighten it first.
