I purchased BMR Springs and KYB Shocks, from Late Model Restoration. Also I got a J&M adjustable pan hard bar, GT500 strut mounts, camber bolts, & jounce bumps from American Muscle. I haven't installed them yet. That being said, I have read good reviews for both springs. My choice was due to the spring rate being the closest to stock. Apparently lowering with stiffer springs and drag racing don't mix. You can find post by Squidd on forums discussing this. Anyway, I am sure someone will chime in on your choices and give you some insight. If you plan on keeping the stock struts, Roush sales some lowering springs that are designed for use with those. Congrats and good luck.
