4E Tactician build?, Need advice on a build, and wireless knowhow. Options

[Shaggy Denai]

So I started creating a build in 4th Ed with the philosophy of battlefield information superiority, a desert wars merc Tactician/comm specialist. most of my experience was from 3rd edition so I had to trawl through some books to find things that would improve my Perception to this end (I have a habit of liking to build ‘niche’ characters with strengths and weaknesses, and a warrior that relied about nous rather than a meat tank cyberware build appealed to me)
Doing a whole orientation system/AR Tactical software/radar/ultrasound sensor omniscence thing, and I’ve been looking into the commlink, somebody said it was cheaper to cobble together a commlink out of unwired and I’ve been pondering the things I would have to do and the programs I would have to have to intercept communications (either radio or nodewise) and decrypt them without being found out and node compromised as he isn’t a true hacker.
Sniffer and decrypt are obvious ones. and I’ll probably be running an processor 6…. as I think somebody told me running programs causes the responce to lower in rating which affects what level programs you can run? (hmmm, can you OPTIMIZE a tacsoft? you have to run three commlinks as slaves to my subscription list) Stealth ECM and ECCM also are big ones.
I still havent finished this, I will probably want to squeeze in the launch skill to utilise the underbarrel launcher on the Ares Alpha (Tactical smoke/flash grenades, yeah!) and probably shift some of the knowskills around to a bit of a broader range
