These are some heavy parts!  They are shipped on a pallet and are really well wrapped and banded.  Fortunately I have access to a loading dock and forklift at work, so I just had the whole pallet dropped into the bed of my Tacoma.  When I got home I had a couple of friends help me unload the parts one by one.  You definitely need two guys to get the posts out of the truck, and watch out for sliding parts!  Once the posts are unloaded one person can easily roll them around on the wheels.

The lift is mostly assembled, but you do have to put a few parts together.  I had to install a few fittings and mount the hydraulic pump to the cart.

I roughly set the posts in place and then pulled in a few cars to make sure the arms swung under without any problems.  I spaced them apart 122", which seemed to fit my Tacoma, E46 BMW and Kaiser pretty well.

Once I was happy with the rough placement of the posts, I laid down chalk lines on either side and squared up the posts to each other.  I also tried to get them as straight to the garage as possible. 

You have to drill ten 7/8" holes all the way through the slab.  This takes a pretty big hammer drill or you will be there for hours.  I started with a 5/8" pilot hole 2" deep per the instructions, then bored a 7/8" hole all the way through.  

I used a coat hanger with a small bend at the end to make sure the slab was at least 4" thick.  It's pretty weird to see the dirt under your house.

I used a Shop Vac to clean out the holes, then pounded in the inserts with a sledge hammer.  This is where you will want an extra bolt to hammer on.  They only send you the required ten, but at least one will get destroyed while pounding in the anchors.
