2:1 Hauling is king - The mechanical advantage of 2:1 hauling will drastically change your wall experience once mastered. What was previously full-force upside-down leg presses to lift a 300lb kit will turn into gentle no-load squats. Gravity does the winching work, and you only use effort to stand back up and reset. Ergonomics are crucial, take the time to perfect the squat depth at a given belay before committing to hauling. A 5-6" stroke may seem demoralizingly small at first, but it really adds up with low effort squatting rhythm. Take all weight off your harness as it increases the energy to stand back up after the squat. Bring a spare Z-cord, as they will sometimes get de-sheathed if weighting over an edge at an awkward belay. See the Mountain Project threads for creating your own 2:1 kit.
Mini Tag Bag - An obvious question for first time multiday free climbers is: how do I free climb with all this extra weight on me? An advanced tactic to manage the load is free climbing with a tagline (~5mm) and tiny foot haul kit (as little as two Traxions on biners + a sling). This small amount of weight hardly affects the leader. Once at the next belay, they use the tag haul kit to quickly foot haul up a tag bag (with the 2:1 haul kit, approach shoes, gloves, a bit of water) and the full size haul line. The leader does need a few extra minutes to then reset for the true haul, but the energy saved is worth it if you have the time to spare. Remember, ergonomics are key! A large, minimal stuff sack is helpful for storing the tagline and can be tied to the tag bag before sending it upwards.
Bag Side Traxion - A Mark Hudon trick for hauling logistics is to use a Micro Traxion on the bag side of the haul line at the load connection point. The Traxion is backed up with a knot just behind it, but the knot is never weighted. This allows you to quickly change the attachment position, and use the haul line tail itself for lower outs. On Corazon, we had a 70m haul line and no lower out cord - it was enough for all but one giant traverse (we used a bit of the follower side lead line to lower out the bags the rest of the way with a bit of knot passing shenanigans).
Docking - A munter mule is far superior to a sling/daisy for docking the bags. When it is time to release the bag, the backup mule hitch can be undone under tension, and then the munter can be used to gently lower the bags off the anchor, no wrestling needed! This is especially helpful if the leader is out of yelling range and they haul the bags tight upwards before the follower is ready to release them. A ~8mm x 15ft piece of cord makes a nice tether for the bag.
Haul Friendly Anchors - It is usually helpful to haul off the highest anchor point to keep things ergonomic. It is also best to avoid hauling off a knotted masterpoint when possible, risking a welded knot if you do. My favorite anchor setup to avoid this is a double shoulder length sling with two medium sized lockers and one mini locker (I bring two anchor kits up the wall). Assuming two solid bolts, I create a knotted V with the medium size lockers on each bolt, with the large basket downwards. The lower V masterpoint is my "free climbing zone", useful for personal anchoring, belaying, etc. I haul high off one of the medium sized lockers, and then dock with a munter mule into the mini locker, hanging off the other high medium sized locker. There is a mini locker for the bag tether on each of the anchor kits, so that when the follower lowers the bag off the mini locker with the munter, they don't have to scramble to clip the mini locker to the tether in order to send it up for the next docking.
