You do want to start at the top don't you? A Colnago frame and Campy 11-speed Super Record for your first build is pretty ambitious, particularly since you say you are a novice at bicycle mechanics in general.
Frankly, given the high cost of all of your components and your lack of knowledge, I'd opt for having the LBS build it up. The first bike I built up from a bare frame and a build kit was after I had several years of increasingly involved bike repair and maintenance experience on simpler and less costly bikes. The build went well but I wasn't a babe-in-the-woods at the time.
BTW, There is no such thing as a "long cage front derailleur", cage length refers to rear derailleurs. The Colnago may indeed have English threading as many Italian makers have gone to it over the past few years. Try e-mailing either Colnago's US distributor or the dealer where you are buying your frame to find out for sure.
I hope this posting doesn't come across as patronizing but I think you are taking on more of a project than you have the expertise to handle and I don't want you to make some very costly, or worse, dangerous mistakes.
