Creak/Pop In the Front End of My Swinger

100% do the offset upper control arm bushings.

if you can find another set(s) of control arms you can reman them on your timeline and then have everything ready to go and attack it all in one fell swoop.

the alternative is buying some arms, and while that's a significant cash outlay the hard work there is already done.

besides the ball joint socket, you'll need a press for the LCA bushings and to create a tool for the UCA bushings to R&R those. although tools are available for both if you wanted to roll that way.
