Have done research but still confused

I am looking at putting better suspension on my 87 gt. I am looking at coil overs for the front. What I am confused about is what parts would I be going about to get this set up. I may sound dumb but I really need some help. I am leaning towards tokico illumina adjustable struts and shocks. I have done research but am so confused. I am new at this so please bare with me. So far I am looking at hotchkiss upper/lowe control arms and tokico adjustable struts/shocks. Please help me with the coil over situation.
Thanks
