The 1300 could be in line depending on the locale and considering they would be using factory OEM parts. OEM parts are almost always higher than the local parts houses. That does not mean they’re gouging you at all. Car makers (all of them) do not provide cut rate prices to the dealers on parts in spite of a general perception that they do.
As to labor, many areas have high labor rates that can run 125 to 200 dollars per flat rate hour. It doesn’t take long to hit 1300 dollars in total.
Price the job around at an independent and as to the other items you mention 700 dollars does not seem out of line for that but some details on the control arm bushings might help clear it up a bit.
