I added two more bolts for the front bumper.

For the front suspension I built a RUF spring pack with the stock 3 leaf pack on the top and a full 4 pack of Jeep YJ springs underneath. The 7 leaf pack seems to work pretty well and not be overly tall. The bottom 4 YJ springs are pretty thin and don't add a ton of lift. Luke from Frontier 4x4 only used 3 of the Jeep leaves in his and the front sits nice and low. Probably too low if you are running larger than 36" tires and don't want to trim the fenders.
