I'm not very clear with what exactly you have for your suspension.
Tokico blues are shocks
. Ground Control sells coilovers
. They are 2 seperate things. From what you are tell us, we are only getting half of the information we really need.
What shocks do you have on the front? What shocks are on the rear? What springs/coilovers are on the front? What springs/coilovers are on the rear? That should help clear things up a bit.
What do the springs on the coilovers say on them? There should be numbers stamped on them that look like this:
Give us the numbers and we can help figure out what shocks to use or if you need to change your springs. In most cases, if you lower a car or modify the suspension, you will have a more uncomfortable ride. Moreso when you use coilovers.
No your GC's are not messed up. To adjust them, you loosen the allen bolt that's in the spring perch and then spin the perch up or down the collar. It is supposed to move up and down easily by hand. When you are done adjusting, tighten the allen bolt back up. Keep in mind that when ever you make significant height changes to your ride height, you will need to have the car aligned. Raising or lowering a car changes camber and toe settings.
