Hey man,
Unless you can afford a real set of competition coilovers such as Tein, Tanabe, HKS just to name a few, then save yourself the trouble and just get springs. Springs have a much better ride quality than the coilover sleeves and are designed for your specific application, including spring rates. Some reccomended spring companies are Eibach, H&R, and Neuspeed. If you really need adjustability then you mix and match...... The coilover sleeve's have extremely high spring rates to accomodate for altering ride hight. The front springs on a coilover sleeve kit are usually not bad in terms of spring rate, it's the rears that are WAYY to stiff....that's where you see those cars that hit a bump on the road and dont stop bouncing for another 100 yards.... next time you see that, notice where that travel is coming from....the rear. You can have coilovers on the front and springs on the back. This way in winter (if it snow's by you) you can raise up the front a tad for snow, and dump it in the summer. But overall, I would just stick with springs.
In terms of camber, it's a general rule that if you lower your car more than 1.5-1.7" you should definately use a camber kit. But once again, it's all to do with your car.
In terms of new shocks....it depends. If you go for something like the Eibach Pro Kit that only lowers like 1.25", then you'll be safe for a while with your stockers.....If you go with something like the Eibach sportlines that lower 2", then your shocks will die very quick considering they're 10 years old.
Best case senerio......get springs and new shocks, or a matched spring/shock kit. Should give you the results you want if you're on a budget.
Once your first album goes.....aluminum....... get real coilovers.
