>>970081>cyclocross touring rigThose are opposite things. Touring bikes have long wheel bases and CX have short ones.
What you really mean is that you want a road bike fitted with 35mm tires, racks and fenders. If you're doing long distance riding then get a touring bike. An OTS could make a tourer, it's wheel base is in the middle somewhere but that and the shifter mounts are the only real difference.
Measure the chain stays and see if your frame can actually fit the tires you want, if it can then read up replacing down tube shifters with brifters or barcons, it's all you really need to do.
It would be cheaper and easier to just buy a touring bike off bikesdirect. It won't be any worse than what you cobble together without any real experience or understanding of gear.
