I'm no expert but the below is what I found useful when I did my hoses and stainless hardline.
For stainless hose:
When I was about to do my AN fittings I found a number of threads about this brand of hose cutters. It worked really well for me making nice clean cuts:

For AN fitting assembly on hose I had good luck with Koul Tools.

Made it a lot easier especially for the little hoses I had to make (couple -4 ones). I found the larger hoses easier to make but they make tools that go from -4 to -16. You can certainly do it without but if you have a lot of hose ends to assemble it makes for much faster assembly especially if you don't assemble AN fittings all the time like me.
There is a couple good videos on Youtube of hose end assembly. This one from Earl's I found good:

Like Greg said don't forget to lube the hose and use anti-sieze on the threads of all fittings, helps a lot.
For Hardline:
If you are planning on doing stainless hardline I would look into Rigid's line of Tubing benders and flaring tools:
Flaring Tool:

Benders:

You will also want a couple cutters. A normal sized one for cutting the hardline off the car and a compact one for cutting to fit on the car, or you can get away with one compact one but you definitely will find yourself wanting to cut a line on the car.
You will also want to champher and polish all ends that you cut in the hardline especially if its stainless annealed (probably not needed for alum) since the stainless likes to split on the flairs.
Hope this helps!
