Don't worry, Jesse, it will surely be easier than you might currently think.

First, use this thread for questions
CIVA INS - THE ONLY THREAD PLEASE : http://www.captainsim.org/yabb2/YaBB.pl?num=1285100008
You can also look up answers there, the ones concerning the installation are very common and therefor already present.

For the Doppler, this thread will be it
Doppler Navigation SPOT ON!: http://www.captainsim.org/yabb2/YaBB.pl?num=1285938402

I recommend a forum search or just a short view in the thread list on the next support item.  ;)
