Ice link, Aux, CD changer cable questions

[Kryptonite]

Okay, I am totally confused after all the info I have read. I've looked at the DIY's on the front page but I am unsure as to what is really going on with some of the installations:

FYI - '03 4.4i w/o NAV & w/o DSP

Does the icelink connect to the back of the business CD or does it connect to the CD changer controls in the rear area?

If I connect the icelink, does that mean I loose functionality of the CD player?

If I add the Blitzsafe XM Direct box, could I use the RCA's for something other than an XM box (like a DVD player or ..... carputer [did he say car-computer? hehe) or does it have to be the XM Direct unit?

After adding the Blitzsafe, do I still have business CD functionality?

I've never seen my MID go to an "AUX" choice; does this only happen when you've connected one of the above-mentioned devices?

What would be the best path to run cables form the MID/business CD area to the rear area where the CD changer and other devices usually go? Would that be a DIY or should I chunk up tha cash?

I appreciate any and everyone's help with this....
