seperating APB

I know several threads have been done about this. However none of them truely address the wire size used.

First, can I use telephone line for the data transmission and the appropriate connectors
Second, what size and type wire for the power leads and what connectors has everyone else had success with.

ultimately I would like to solder everything once but use a connection point in such a way that I could patch in additional length if the layout changes /grows. I don't think the connectors would provide enough ressitance to cause lag or problems when SSDC is added, but I could be wrong.

Thanks in advance for any answers.

I swear if Mr. Flippant is the first to answer this question I will just start asking him first and save everyone the trouble of reading next time.
