Some are happy with Danny and his kits, some like to tweak and use his "upgrade" kits, personally I'll pass. Personally I'd build Dennis Murphy/Philharmonic Audio's kit first
http://philharmonicaudio.com/aa.html or a variety of kits from other sources first (diysoundgroup.com, Madisound, Meniscus, Parts-Express). I did build the Parts-Express BR-1 kit before Dennis offered his versions, too.
The speaker wire and other types of cabling thing has been beat to death and is certainly not a worthwhile use of money or time as long as you choose appropriately, and it definitely need not cost very much.
