Front End Suspension Work

[JMan300sd]

Hi Guys,

So I was driving at 70 mph on 1-95 the other day and coming off the off-ramp I heard this loud pop and saw some black piece of rubber fly out from underneath my drivers side front wheel well. The car kept driving fine so I continued to my destination. Upon arrival I take a look under there and notice the outer bushing, washer and bolt completley mssing from the attachment of the Sway bar to my upper control arm!!! Well I found some rubber bushing material and fit it in there with a new bolt and large washer. It got me home and I have been driving it like that for a week now, but it is far from tight

The whole thing has prompted me to review my whole front end. A few questions:
1). On the upper control arm the ball joints look really good. Can I just replace the bushings to the sway bar without having to replace the whole UCA? Where can I buy the right size bolt and washer/fitting for this joint?
2). The ball Joints on the LCA look terrible and the boot is definetly torn. This sounds like a big job....should I even attempt this?
3). I plan on replacing the tie rods and front struts while correcting the issue with the UCA....what else should look at and how will I know if it needs replacing?
