Yes, proper bearings on the struts make the steering smoother and lighter especially for town driving.
They're not a substitute for power steering at parking speeds though, especially with wider tyres.
I fitted mine when my last front shox wore out so took the opportunity to fit the bearings whilst everything else was off the car. I can't see how they can be changed without removing the struts completely from the car since IIRC you have to remove the springs with compressors etc.
I don't think the ride height changed much. My lowered springs after 20 something years have lowered themselves a bit more so an extra 1/8th on the ride height doesn't matter if it happened. When I was looking there were 2 kits available. One used Ford Sierra bearings, the other a type of needle roller bearing. I believe the latter was thinner if you're really worried about adding ride height. The usual suspects such as Robsport and S&S sell the kits so you get fitting instructions and help if needed.
Definitely worth it though[:)]
