Go to the Tech Articles, Hard top install by Brian Liang.
It is all there as a PDF
Installing took me 4 hours on my own, 2 hrs with a buddy. You will need a beer and lots of water to start. Get a punching bag (not your buddy though you may need to be his bag). It is not that big a deal, just the front edge over the windshield lineing up, if on your own it is a big thing to manuver around. The pieces fit together nicely, it's just that the top slots over the side and corner panels in such a way you can not reach the bolt and the nut on your own without a clamping wrench.
On the install I needed 2 clamping wrenches, several socket wrenches (I no longer recall the sizes needed but several - UK engineering so loved - socket extenders and that is about it.
If you are there for a day or two, I recommend to caulk the rain gutter. Mine leaked in all the bolt holes until I ran a bead of caulk on everything - then really water tight after that.
