check out South Jersey Wheelmen or the Clay Club (De?) for rides or links to info. Adventure Cycling.org is another link to several levels of touring info.
SJW has "Get Ready Metric" in May, a good generic starter to road riding for the season! this starts in May (5/07), at Fort Mott, nj (2 miles from salem, 10 miles from Wilmington), a good practice for a tour!
bf can offer much more info, but will need more specifics on your idea of tour distances, time, level, etc.
are you going x-USA, around the block, what are your specific goals?
good luck, and again, Welcome!
