Sound is pretty much like dry ball joint. Try to clean them up on outside so that dirt does not get in, peel back rubber boot a bit, spray some grease/oil in there and see if noise goes away. If it does you know where it's coming from but to sort them out properly would need to clean old grease out and pack with new grease if there is no wear in them or replace if too much wear.
Bushes does not look good but I would not say that they are shot. As long as there is no excessive movement they should be fine. 2-3 year old bushes can look like that but last for another 7 years before needing replacement.
