I don't think it would hurt. I changed the refresh rate of my laptop's LCD from 59 to 60 a month ago and its been working fine since. As long as 60 Hz is already shown as an option in your control panel or whatever, it should be OK.
Probably because the screen's refresh rate is too low. See the maker's website or user guide for instructions on increasing the monitor's refresh rate.

By shaky I assume you mean the monitor is flickering, you can fix this by raising the refresh rate on your monitor. Ideally the native resolution and refresh rate work best, most often this is the highest refresh rate supported by your monitor, and the largest resoltuion supported by your monitor. Try changing refresh rate to 60 Hertz first, if it continues flickering, then keep raising the refresh rate until the flickering stops. (Don't forget to click apply after changfing the refresh rate to ensure the refresh rate is changed)
