tundra bilstein 5100 shocks and tundra coils up front with landcruiser coils and shocks out back is always a good option. It can be pieced together for cheap and its a well-performing setup on and off road. You may get too much lift in the rear though. When I was stock weight, I was getting 4.5" of lift out of my landcruiser 7.5 wrap coils.
Keep in mind that you will want to also buy a front differential drop kit (not too expensive at all from toytec) if you are lifting the front 3". Even still, you may find that your CV boots start leaking grease after you lift it, which means you will have to reboot them or replace them altogether - just one more cost and process to deal with.
In addition, when you reach 3" of lift, you will not be able to get your alignment fully back to toyota's specs, unless you purchase after market upper control arms. These alone will cost more than you are probably willing to spend on your lift. I am not running them with my 2.75-3" of lift and its bearable. My caster is just low, so it doesnt track as nicely on the highway. You get used to it, but it's not amazing.
Also, an extended rear brake line is not mandatory, but I would recommend it as well.
Sure, there is the logic that you should just wait and save up for the bigger lift, but you have to keep in mind that the higher you lift it, the more small problems you will run into, especially in the front.
