lift problems

[88-3/4t-bad boy]

i have a six inch lift on my 88 burb. and i want some more clearance for the 37's im going to put on it. i was thinking of replacing the 2 inch block in the rear with a 3" block and adding a zero rate from ord on the front for that extra inch. the question is do i need to replace my shocks for this or will they be fine? i have dual shocks on each tire so i really dont feel like replacing all of those. also, steering components? and would i have to lengthen my driveshaft like you have to on the 8" lifts
