Disk brake help

Ok well I'm gonna tear into it this weekend. I already ordered the parts and will deal with problems as they come up. I already found the upper ball joints are loose and someone removed the outer cams on the upper arms. Oddly enough I found the cams in the ledge forward of the upper arms, same as with my Duster. I wonder if this was some regular practice on these cars? All the other rubber from the dust covers on all tie rods/ball joints to the forward strut/ lower arms are rotten. But luckily no metal degradation like on my Duster. No fill welding needed.
I don't have a front sway bar to deal with. I know this is off topic for brakes but can anybody recommend a sway bar for a stock Demon/ Duster? While I'm in here Id rather just do the upgrade.
And while I'm on the subject of brakes can anyone suggest a booster or what I need to do to add one in for a car with disk without booster? I have looked over the rear and there seems to be a check valve of sorts for the rear drums. I'm really flying blind here. If I have to buy redundant parts I don't mind. I want this car safe for my wife to drive if she needs to. Sounds crazy but I want her to be able to drive it if she needs to with the ease of a modern car. Yes I still love her more than my Demon even if she doesn't think so.
