4. Sorry about that - yes Target (not the department store) makes thick plastic discs that the spikes rest on. I used them for my speaker stands before getting the Dalis as I had monitors previously. I was going to use them again, but I see the Dali spike set comes with discs that have felt underneath. They will make sliding the speakers out away from the wall a lot easier, so I will be going with them. I haven't put the spikes in because clearly, it is a two person job and I haven't had a chance to invite my buddy over yet.
6. Room treatments - We've probably done just about everything wrong in the room! We had nice wall-to-wall carpeting, but we pulled it up and put down hardwood instead. There is a leather sofa and loveseat. The tables are glass! FWIW, there are heavy drapes on the window at the far end of the room (opposite the speakers). I draw them when listening. There is an area rug and an upholstered chair, plus there are canvas pictures on the walls (as opposed to glass framed pictures). There are also some plants in the two far corners on either side of the window. But I've got two large wooden cases that hold my CD collection, so the CDs are also probably reflecting a lot of sound.
I am limited in what else I can put in the room to absorb sound and to reduce reflection points.
3. Calibration of your speakers so they are at the same level is essential so you do not have one speaker/s playing louder or softer then the others. In essence, you send test tones through each speaker at an individual level in conjunction with a measurement tool, a hand held SPL meter which most people purchase from Radio Shack. The test tone is either generated within the receiver/surround sound processor (SSP) or an AVIA disc and then calibrated and adjusted from your main listening area measuring the output of the DB each speaker.
You may want to do a search on AVS for further information.

4. Again, I am not familiar with your choice of discs to protect the wood floor. I use Cone Coasters for my monitors which are on stands with spikes. They work very well and provide the ability to slide the speaker if needed due to the teflon bottom. Due to owning monitors, I just take the monitor off the stand and then slide the stand/s when I need to move the speakers. The 800's are very large speakers and you will need help to place the discs under the spikes if you go that route. That is also one of the reasons I went to monitors as the floor standers can/could be cumbersome for placement.
I used this product and placed the Dali 400's on top of them when I owned them because I did not want to deal with the spike issue and the discs with the 400's. This product makes it easier to move the speaker if needed as it has a handle on the front of the riser so you can pull and slide the speaker on the Gramma riser. I am not sure if aesthetics would be an issue with this setup for you. They never really bothered me.http://www.auralex.com/sound_isolati...ion_gramma.asp
6. I don't think you've done anything wrong with the room because when you have an audio system in a room that is not dedicated, there can always be issues. If you've put area rugs down, items on the wall and filled the room with normal items, this is life. There are always trade offs unless the room is dedicated. You do what you can. You may want to pose in another thread your concerns. There is an area on AVS that deals with this issue.
I'd suggest setting your system up and see exactly what your impressions are of the output when everything is in place. If you are not happy, then take your wife/GF to a 5 star restaurant, buy her roses and convince her you need room treatments.
Other opinions should be solicited as there are some sharp guys on here with a lot of experience.
