Are there any Bike pros who could give me some specific tips on bikes?
The how-to department right here on the ACA web site is the first place to start:http://www.adventurecycling.org/features/buyersguide.cfm
Take this list and see if any of these bikes are in stock in your area (unlikely). Then ask which of these bikes can be ordered by your local bike shop. Ask if any of the staff at the shop is a touring cyclist. If so, ask for advice. Then ask if you are committed to purchasing if you have them order in a bike for a test ride. Find out how they will determine what size to order. And ask if they promise to work with you as long as it takes to make whatever bike you end up with fit well and be comfortable.
Make sure you understand as much as possible about what you plan to do with this bike. Most people are inclined to say "I want a bike that can do everything." This is a bad idea as that bike will probably not do anything well. If you are trying to buy a touring bike, e.g., don't try to also make it your "go-fast" bike. You won't like it for either.
Here are some questions to ask yourself, and remember, try to make your answers narrow. Figure out what you will do with the bike most often, not everything you might do with the bike sometimes. Are you doing to tour mostly on paved roads or on dirt? Are you going to tour mostly in first-world countries, second-world countries, or third-world countries? What is your budget? Do you want something completely bullet-proof, or are you willing to risk some problems to save some money (note: some people like to solve problems)? Are you going to carry camping gear? Cooking gear? Do you like to take all the creature comforts, or run lean and light? Are you going to use panniers or a trailer? If panniers, two or four (I recommend four)? Are you also going to use the bike for commuting (that's about the only other purpose I'd suggest you plan for)?
Everybody has their own favorite bike, and we tend to naturally like the one we have. That's good news. If everybody likes the one they have, that means that all the bikes mentioned in the how-to department will do just fine. Very few people have ridden all these bikes and can give you an honst first-hand comparison. Don't try to find the "perfect" or "best" bike. Just try to find one that will work for you.
Buy it sooner rather than later. You want as much time with it as you can before your trip.
