You are asking a lot of questions in one sentence so I will try to answer them as best as I can.
Springs- What are your goals. stock height, lowered, firmer, same spring rates? reduce sagging, increase spring rates. Many options from stock to aftermarket.
Shocks- Monroe severe service for the budget minded or blisteins.
Sway bars- price range? For the budget you can go f body front and ho/ha rear. Or you could buy a kit that has front and rear bars. Or keep your stockers and put new endlink and bushings up front if your cheap.
Rear lower control arms- BMR are the cheapest but no matter what its a good upgrade and just about mandatory with aftermarket bars to prevent the mounts from ripping through the lca.
Body Bushings- Do a search on body bushings and you will find multiple lists of part numbers of what people are using. You can replace the missing lowers only, replace all lowers, or go all out and replace uppers and lowers.
Front suspension- Try Zack at the previous link posted for the super front end rebuild kit. He currently has them on sale.
Bumpstops- use ZQ8 (2) 15956547, $7.65 x 2 = $15.30. Order from Dal / dealer.
That should put a nice dent in your wallet.
Here is what I am doing and I am on a tight budget. my setup
I would recommend doing a search on each part you want to replace and determine your budget. That will ultimately decide whether you will factory replace everything or upgrade to aftermarket.
If you want more part numbers or information I have been gathering it much over the past month.
