Front ball joint question/ help please

[ChevyDude]

I am changing out the front spindals and springs, going with ECE 2.5" drops and Ground Force 2" drop springs. I've got the springs out and the spindals off and was wondering is there anyway to change out all the rubber around the ball joints? Should I replace the ball joints on the upper and lower control arms? If so how do you remove the ball joints, aren't those big rivets? I want to put new rubber between the tie rods and sway bar,,,where should I buy it? I am going to have the control arms soda blasted so maybe it would be a good time to replace the ball joints or if I can just replace the rubber bag that holds the greese??? Any help would be greatly appreciated!!!
