Hey man and welcome! Great to see another from Colorado too!
As for your questions, your springs were done correctly if you made sure they sat in the buckets properly, which would be hard not to do. As for your second question, you really got to be cautious how extreme you wanna go, as a stiffer, well oriented suspension would be better handling, you will loose A LOT of ride comfort and overall long trip drivability unless your springs are progressive, and you get adjustable shocks and struts ect. I have heard really good things about subframe connectors for road applications around here, but I am no expert.
As for caster/ Camber... Factory strut adjustment SUCKS! Get a set of Steeda adjustable 4 bolt strut plates off of a reputable site, or ebay. If you wanted to do something a little cheaper, I know a guy on the forum who is selling some adjustable struts, and the upper caster/camber plates.
Hope this helps, good luck and hope to see you not only on the forums but on the roads as well (I-25 baby)
