I finally got started putting down my floor this weekend. Got about 450 of my 700 square feet down in the living room and master bedroom. Two smaller bedrooms to go. Some observations from a flooring novice:
Saber Saw w/ wood blade
8" Miter Square
48" Steel Ruler
15" Roughneck Utility Bar (for removing staples)
Miscellaneous shims and screws
I am going over existing hardwood. I removed all the carpet, pad and staples then just vacuumed and wet mopped.
Staples are my nemesis. When you think you got rid of all of them, one reappears under the end of the plank you just locked down, so you must remove it and it knocks four others loose.
Clean really well before you begin.
Durham's Water Putty was a cheap and good fix for the low area where a wall was removed. I also used it to fill some other spots where I felt there was too big of a gap or holes from running wires and such.
The score and snap method is the best way to make straight cuts. I found you can cut it with a power miter saw, but it actually takes longer and makes a big mess. I used a $3 eight inch miter square from Harbor Freight as a guide. A 48" steel/aluminum ruler comes in handy for making horizontal cuts. It can be tough to keep everything straight while cutting since it is somewhat slippery.
A saber saw is the best way to make curved cuts or notches around door jams. A regular wood blade works fine.
It took forever to get my first few courses down. The wall I started on was not straight. I used the existing hardwood lines as a guide to make sure the floor was straight, but I did not do a great job shimming it well and things kept moving around on me.
In hindsight I would have been better off putting down a single course about 10 inches from the wall. Once straight, use scrap pieces of Allure screwed to the floor to prevent movement towards the wall. After the rest of the floor is layed and there is plenty of weight, remove the scraps and install backwards towards the wall. It would also help plan out room to room transitions.
Get good kneepads - I didn't and I'm paying for it today. Gloves would also have been a good idea as I spent two days scraping my knuckles on the floor, but the clunky leather gloves I had around were too bulky.
Use a scrap about 2x2 to tap in planks with a rubber mallet. I got lazy a couple times and just used the mallet and damaged the locking tab slightly.
Use a small crowbar/nail puller to drop and lock strips along walls.
I'm doing great on scrap with only about 5% through 23 boxes. I have many 48x4" planks that hopefully will be recovered when I hit the back wall of the house. Only had one damaged plank with a bad corner, which could have been from my handling. The boxes are extremely slick and slide around like crazy. Make sure you secure them well when transporting or you may end up with 1000 pounds of floor flying into the back of your SUV seat if you stop hard.
