If you see any power steering fluid leaking from either one of the accordion boots over an inner tie rod end, one of the end seals is leaking in the rack and pinion assembly, and you are right, it needs to be replaced. Most of the time new racks come with new inner tie rod ends already installed so you'll be handling all the problems at the same time.

One potential cause of a shaking steering wheel while accelerating at lower speeds is a worn spot inside an inner cv joint housing. That can be real hard to identify, and a belt in a tire starting to break can give the same symptom. You might try switching the two right side tires front-to-rear and see if the shaking goes away. If not, switch the two left tires and try it again.
