I wanna level and drop my truck, HELP please

[MrMilks]

I just want to level it out and do a drop that I can still fit 20's with no clearance issues. I have been told I could just buy some shackles for the rear from auto zone that will cost me 40$ and I can get 2 inches out of them. Is that enough to even level it out? I have I have also heard I could just remove the bottom leaf out of the rear and that will give some drop. Just let me know what the best way is of going about this for the front and rear. Thanks.
