Help ...
1)Intercom:
http://www.cockpitbuilders.com/community/index.php?topic=1919.msg14738#new

I am pretty sure that some cable shielding  to the jacks is required.
Need a guide for dummies on the subject

2) LED strips 12v.

I want to have 3 stripes on he same dimmer
One above MCP ,2 feet
Two for the Glare underwing openings, 5 inch each

Better to feed them parallel (easier wiring ) or series , For LEDs I think it does not make much diff but just checking your experience

1: Intercom - Since we are talking about simple voice communication at audio voice frequencies, the voice frequencies are much too low to worry about interference I would think. But shielding would certainly not do any harm.

2: Don't know how LEDs in a strip are wired together but if the LEDs are wired in series, then mistake to add another strip connected in series to the first strip since both strips will split the supply voltage in direct proportion to the length of the strip & number of LEDs. Since the strips require 12V, I would assume the LEDs are wired in series

But if the LEDs in a strip are wired in parallel to each other, then hooking up both strips in parallel would be ok as long as both strips require same supply voltage. But I doubt that is the case unless the strip incorporates a way to limit the voltage to the LEDs since they would fry with 12 volts

As for "LED-strips".

They are intended to be cut at specific and marked points on the tape.
At the cutting points you have clearly marked solder terminals on both sides of the cut mark.
You connect them parallel = connect +12V to the + terminal of the cut strip peace and ground to the - terminal.
No risk of "frying" them as they always are protected with built in resistors.

Some strips are not easily cut enabled, but they are rare. 
Those give minor solder problems when you cut them - very small terminal points.

Intercom terminals.
No need to have those "shielded" as Maurice said.

Good to have you onboard!
Thanks guys
