Sounds like good advice, with a couple of suggestions:
Any travel agent worth his salt works with consolidators these days, and he'll know which ones specialize in the area you need. Most consolidators have wholesale rates sold only to agencies, and a slightly higher rate sold to the public. Chances are a good agent will save you a little money and a lot of time shopping.
Consolidators are now getting their fares as much as nine months in advance. An agent only has to look for the appropriate booking class to find you the best deal.
One caveat: consolidators do go out of business, sometimes before paying the airline. In that case, you're probably out your money and the airline will refuse to board you unless the pay their walkup fare. Be sure you know who you're dealing with and use a credit card to purchase your ticket. It gives you some protection in case the consolidator goes under.
