So I know I'm going to get the rear sway bar but are the front and rear end links worth buying? I know racing line products are excellent but those seem like parts that might not make too much of a difference.

i used to have them on my car and believe me, get the rears for sure with the sway bar combo. for me it made a big difference when it came to stiffness around cornering or taking fast turns. i also had the fronts but it didnt seem to make a difference.
idk if it was because i already had the stillen strut bar before i installed the front end links.

^what he said
Def get the rears. Do it at same time you install RSB
