You are picking expensive parts to do a low budget install with. Substitute the:
KP kit-> suicidedoors 4-link and brackets (450?)
Aircommander -> 1 Viair 450 (200)
Easy street front -> bags/cups/shocks from innovative (350)

Thats leaves you with a lot of money for the airsupply and other things you will need like rear shocks, rear bags, misc parts you will find out you need while installing. etc...
