Re: Sierra 2 questions (stands mostly)
Any decent stand should work well, just try to find the correct height that will place the center of the tweeter at approx. ear level. Ascend offers one on this site. Some people actually use the CMT-340 pedestals as stand for their Sierra's, although they are only available in standard black unless you can get a custom finish. Filling stands with sand or shot is done for several reasons: 1) It can dampen any resonances out of the support tubes, and 2) It adds stability to the stand which resists tipping over better. Usually the stand will state if it is fillable.
All stands(at least the decent ones) include bumper pads that stick on to the top of the stand for the speaker to sit on which decouples it from the stand eliminating vibration. You can additionally use a putty-like product called "Quake-hold" or Museum wax to affix the speaker to the stand to further secure it.
The speaker terminals on the Sierra's will accept most types of wire terminations(Bare wire, Spade, Bananas, pin) so use whichever you prefer. If you will be connecting/disconnecting frequently then use bananas. Blue Jeans cables seem to get great feedback.
