Sounds like just a freshen up, not an upgrade, so probably don't need bump steer and new torsion bars.
Front - I assume you mean just the front strut inserts not new struts. If you don't track the car, you probably don't need that camber brace either. Rear - If by sway bar brackets, you mean the stronger ones, good. Not sure why you need new drop links. This a wear item on the newer cars?? What about brake caliper rebuild kits front and rear to freshen them up as well. News seals, etc.

Inspect for wear and replace
Front: A-arm bushings Rear: Control arm bushings

How would you check for wear on these? And when you say control arm are you also meaning the swing plate bushings? The reason I ask is I just elected to keep mine based on Waynes book.. I think it says that he does not recommend replacing unless they are cracked as nothing is as good as the original bushings there. When I had mine all apart I played with the bushing on the control are or swing axle or whatever you call it.. the ones near the transmission.. I simply noted that while they were sort of stretchy, and pliable, they were connected and not broke.. is that a "pass"? I'll do a search also on this but I thought Id ask if you dont mind (like you had a choice).

Your control arm bushings front and rear will be shot .The rubber deforms with age and weight to an oblong shape.If the front end knocks over bumps look carefully at the torsion bars for telltale grooves from metal contact(because of worn bushings)The bars can probably be reused but look at the groove and smooth it with emory at least. I have used Weltmeister poly up front(with grease fittings) and neatrix at back But have only put about 20000 mi on in last 4 years so can,t vouch for long term The ball joints may be passable but worth changing with anything over 75000 mi. The wheel bearings will probably be OKand reusable if they,ve been cleaned and repacked at least once in their life. Check brake hoses for cracks and look at any rubber parts such as fuel pump hoses while under the front end.

The rubber sags over time, allowing the torsion bars to ride on their housings. This results in squeaks and a harsh ride because the metal is grinding itself away and the bumps are transmitting energy right through the metal, not rubber.
This is especially common in the front. If you let this condition continue for much time, you will need new torsion bars.

Poly-Bronze bushings are best. They have much less friction than stock rubber, even when the rubber was new. This allows for freeer suspension travel. The ride harshness will be lessened. The ride stiffness is determined by the torsion bar spring rate.
