Lift Kit and Tire Size Advice

Good evening Taco fans! I'm a new owner of my third Toyota Tacoma. I just purchased a 2010 Double Cab TRD Sport. My question goes out to anyone who might have experienced or have knowledge on the Ultimate Lift Kit by ToyTec. The kit comes with four Bilstein 5100 shocks, two front coilovers, and two rear add-a-leafs for $1149. Not sure if this can be purchased elsewhere for a much lower price, but I'd like to either purchase the 18" or 20" Ballistic Jesters and put them on 33" tires. Although the 18" wheels may be more realistic, what's the probability of either wheel fitting on my Tacoma with a 3" lift? Will it rub? Lastly, what's the largest size tire I can use on either wheel if I wanted to use a Mud Terrain or Light Terrain tire such as the Cooper Discoverer Radial STT Tek3. I'd like to have an aggressive look without having to worry about the tires rubbing whenever I turn a corner. Any help or advice given would greatly be appreciated! Thanks again!
