Wheel bearings/ rotors/ brakes etc...

[AU-MUSTD]

Hi all i'm going to be changing the pads, rotors, tie rods, ball joints, wheel bearings, fuel filter , oil and filter on my fairlane this weekend and just want some advice or any tips, on what can hinder a smooth opertation? Also what can i expect to pay for bearings and ball joints roughly as i've gathered all the rest. Anything else l should do whilst i'm at it??
