While driving at night my headlights dimmed and the engine died. alternater was faulty,replaced and now engine turns over but will not fire, could I have loss a sensor

seems lower then the valve cover?

I had an oil change recently and was informed I needed to replace power sterring hoses and transmission cooler lines as well as a valve gasket. I planned to spend money in reparis but am on a budget. Which of these should be complete first?

I recently replaced the right driver side bearing and hub assembly due to shaking when I brake. This problem was worse after a prlonged period of braking. The problem is still present. Greased the caliper bolt today. Help!!!!
