Long Haul Trucker is a nice bike!
Are buying it from the LBS? Do they seem to take a real interest in fitting you to the bike?
Some bike shops are better than others when it comes to fit. It may be advisable to educate yourself so your BSometer is calibrated when listening to the shops advice.I would recommend Lennard Zinn's advice on bike fit in "Zinn and the Art of Road Bike Maintenance" or there may be some threads of interest in his tech column at VeloNews.com.
But yeah, you have the basics. Some bike shops are really good at swapping handlebars, stems and crank lengths to help tweak the fit. Others charge for it. Be nice to know how they do it up front.
