Changing from stock to 5100's 3 inch lift Toytec

I currently have the 3 inch toytec spacer lift, love the look of it but I am really, ready for a better ride the truck has 100K on it and I think I have just maxed it out. I already have the AAL in the back and was just going to replace the struts with new 5100 Billys all around. But I need some new coils. Any suggestions on how I should go by this? I am just going to take the spacers off the front and add the p reassembled coils and struts in. Will I have to do anything else? What should the Billys be set on in the front. About to order the lift and trying to figure out how I should go by this. Pictures below is what the truck looks like now love the look. But really thinking going wth the 5100s I'm going to have a way better ride.
