I assume your monitors are VESA compatible. The arms will come with all the mounting hardware required. I have a mechanical keyboard and think I type pretty hard but I do not see any wobble with the arms that I have. Some arms will let you rotate the monitor 90 degrees, some will let you tilt, angle, etc.
Something like this would probably work:

I have the single monitor version of that and it was ok for a while but it didn't feel sturdy enough for the 32" I had a the time. Shouldn't be a problem if you have 24"
