Apart from the usual screwdrivers / plieres / socket sets / timing light / axle stands etc , heres a few tools i have found to be very useful for working on my dub (and others too)
Pipette
Very useful tool for removal of brake fluid and other fluids.
DeadBlow Hammer
Great for persuading brake drums off that are stuck without much risk of damage to the drum.
Griping Pliers
These are great for rounded off brake pipe unions / nipples / bolts as they grip tighter the more you turn. Nearly always removes stubborn fixings allowing replacement.
Brake Shoe Hold Down Tool
Does not look much but good for holding the shoe hold down clips and twisting them on easily.
